You ever look at the schedule when it's released in April and just quiver at the thought of seeing a certain player during the upcoming season.
Jaguars' fans quiver twice a year when they know Andre Johnson is coming up.
But there are players league wide that just give Jacksonville fans goosebumps.
Here is a list of all the players Jaguars' fans know is going to give them fits.
There are some on offense, some on defense, a few obvious names and a few surprises as well, but these are players from each team fans do not want any part of.
Bears' defensive end Julius Peppers is one of the best in the league at his position.
He finished with double digits in sacks (11) for the seventh time in his career.
For the Jaguars though, Peppers causes problems to young quarterbacks like Blaine Gabbert.
Gabbert won't realize just how talented Peppers is by hearing about it from coaches and watching film. By the time he does realize it, he'll be picking himself off the ground after being sacked by him.
Young quarterbacks need a lot of help at that stage and protection up front is a top priority. A young quarterback under pressure means sacks and turnovers as they may not be able to handle it just yet.
Either way, Jags fans do not want to see Peppers.
A lot of fans hate to see A.J. Green, but especially the Jaguars fans.
The Jaguars, for a couple seasons now, have struggled against big-play receivers, and Green goes right into that category.
Against the Jags last season, he caught five passes for 90 yards and a touchdown.
His touchdown came on a 37-yard deep pass on 3rd and 17.
Green is a receiver that can get vertical quickly, which poses problems for the Jaguars secondary.
So Jaguars fans, when you see Bengals on the schedule, know that Green will be routinely taking the top off the Jags' defense.
Another guy that can get vertical quickly is Stevie Johnson from the Buffalo Bills.
Johnson may be a bit of a knucklehead sometimes, but when he has his head on straight, he can be a productive receiver for the Bills.
In 2011, Johnson caught 76 passes for more than 1,000 yards and 11 touchdowns, so he is a gamer.
Again, Johnson is a guy that can get down the field and stretch the Jaguars' defense—something that has given them problems over the last couple of years.
Jaguars fans would hate to see Tim Tebow, partially due to on the field reasons, but also because of what could have been.
Tebow could have been a Jaguar if they took a chance on him and all of that Tebowmania, whether you liked it or not, could have happened in his home state of Florida and not Denver.
Tebow causes problems for defenses, no doubt, but for Jaguars fans, seeing him running the Wing-T to perfection and winning against the Jags would hurt just a little bit more.
Who? My sentiments, too, but Ogbannaya did damage to the Jaguars in 2011.
The Browns don't have much to work with, but apparently Ogbonnaya was the guy back in Week 11, when he had 21 carries for 115 yards and a scored a touchdown.
On a regular basis, Jags fans don't want to see Josh Cribbs—last season, it was Ogbannaya.
Ronde Barber may not be what he used to be, but he still has the ability to prey upon young quarterbacks like Blaine Gabbert.
He had only three interceptions in 2011, but one of them came against the Jaguars during the Jags destruction of the Bucs in Week 14.
Barber is a veteran who knows the tricks to the trade and will use them against a quarterback like Gabbert, who may not know them quite yet.
This wasn't as cut and dry as most would think.
Larry Fitzgerald isn't the only playmaker in Arizona anymore—they now have cornerback Patrick Peterson.
But if Jaguars had to choose between who scares them the most, you almost have to go with Fitzgerald.
Fitzgerald has never had any big games against the Jaguars, he's only scored one career touchdown against them in two career meetings.
Last season he caught 80 passes for 1,411 yards and eight touchdowns without a stable situation at quarterback.
Philip Rivers may talk a lot of trash. He may have thrown 20 interceptions in 2011, but he absolutely tore the Jaguars apart on Week 13 on Monday Night Football.
Rivers completed 22 of his 28 passes for 294 yards and three touchdowns and zero interceptions.
Rivers looked like his usual self against the Jaguars, who simply could not keep up with the Chargers. In his previous two games, he had three touchdowns and two interceptions.
Then, he got right back into rhythm when he saw the Jaguars on the schedule.
Dwayne Bowe may be inconsistent at times, and he may not even be in Kansas City for much longer, but he's a player the Jaguars' fans dreaded seeing when the two teams met in 2010.
Bowe caught only three passes, but it was for 81 yards and two touchdowns, including one for 53 yards.
I hate to beat a dead horse, but the Jaguars have had trouble stopping receivers who can stretch the field and Bowe took advantage.
Whenever Jaguar fans see the Colts on the schedule, they know Dwight Freeney is going to cause problems.
Unfortunately, they see the Colts twice on the schedule every year with them being in the same division.
Freeney has year in and year out given various Jaguars' quarterbacks fits. Whether it was Mark Brunell in Freeney's rookie season, Byron Leftwich for years, David Garrard or now Blaine Gabbert, Freeney has routinely sacked quarterbacks.
In 17 career games against the Jags, Freeney has collected 10 sacks, but his sacks in key moments for the Colts against the Jaguars is what gives fans nightmares until this day.
A prime example was when he sacked Garrard on the final play of the game in Jacksonville back in 2008.
I am sorry Jaguar fans for bringing that stinging memory back up.
Another pass rusher that would give Jag fans nightmares is DeMarcus Ware.
Young quarterbacks usually get happy feet in the pocket, which plays right into the hands of Ware.
Ware doesn't have any career sacks against the Jags, but you still have to be keenly aware of him.
His 19.5 sacks in 2011 doesn't necessarily make people think he's incapable of sacking Jaguar quarterbacks.
When fans see the Cowboys on the schedule again in 2014 (unless the two meet in a Super Bowl between now and then), Ware will still be a guy people will have to look out for.
Brandon Marshall has had two big games against the Jaguars in his short career.
In two games, Marshall caught a combined 16 passes for 231 yards, 133 of which came in his first game against the Jaguars back in 2007 as a member of the Denver Broncos.
Marshall has that big-play ability that have plagued the Jaguars' secondary for years.
Speaking of big-play receivers, DeSean Jackson is probably at, or near, the top of the list of the best big-play receivers in the NFL.
Jackson has only played one career game against the Jaguars, but it was a game that is etched into my memory.
Jackson caught only five passes, but they went for 153 yards and one touchdown.
His lone touchdown went for 61 yards.
Jackson doesn't have games like that all the time, although he is certainly capable, but it was something about the Jaguars' secondary he particularly liked.
Couldn't just have one guy from the Falcons because both of these players equally handed the Jaguars their lunch last season.
Let's start with Roddy White who caught 10 passes for 135 yards and two touchdowns against the Jaguars.
White has only played two career games against the Jags. In his other outing against them, he caught four passes for 81 yards.
Now John Abraham. In that same game when White had a career night, Abraham had a career resurrection with 3.5 sacks and two forced fumbles.
Gabbert and Gary Whimper are probably still having nightmares of Abraham, and the same goes for the Jaguars' secondary about White, despite having a ton of injuries going into that game.
Patrick Willis is probably the best linebacker in all of football and his numbers show it.
This past season was the first time in his career that he didn't record more than 100 tackles. He was only three shy of the mark.
Willis is the leader of the 49ers' defense and always seems to be around the ball.
In his one game against the Jaguars in 2009, Willis was credited with 11 total tackles and a half a sack. He, along with the rest of the 49ers' defense, held the Jaguars to a mere three points during that game.
Justin Tuck has only half a sack in two career games against the Jaguars, but he still strikes fear into the hearts of fans across the league.
Jag fans still know that he is more than capable of recording a game with multiple sacks.
With tackles that are questionable in pass protection, it would spell doom for young Gabbert.
Darrell Revis is the best cornerback in the NFL, but doesn't have any interceptions against the Jaguars.
But you don't measure a guy like Revis by interceptions. An example of this was Week 2 against the Jaguars when Revis didn't catch any interceptions, but Jaguars quarterback Luke McCown still threw four interceptions.
Because Revis cuts off half the field, forcing guys like McCown to go another direction, where most of the Jets' secondary is.
Every interception McCown threw was on the opposite side of the field of Revis and into double or triple coverage. This just shows how afraid people are of Revis.
Don't worry Jaguar fans. You're not alone in not wanting to see Calvin Johnson going up against your defense.
The Jaguars join 30 other teams in that category.
Let's take a look at why teams don't want to see Johnson: in 2011 he caught 96 passes for 1,681 yards and 16 touchdowns. My goodness. In the playoff game against the Saints, he caught 12 passes for 211 yards and two touchdowns.
He amassed at least 100 yards receiving in seven games, went for more than 200 in two regular season games, including that insane regular season finale against the Packers, where he went for 244 yards.
Need I say more?
By the way, the Lions are on the schedule for next season.
Surprisingly, despite being in the NFL since 1998, Charles Woodson has only played the Jaguars twice in his entire career and has not recorded an interception.
The last time he played the Jaguars was 2008.
However, Woodson has preyed upon young quarterbacks lately.
In 2011, Woosdon caught seven interceptions and had two games where he caught two interceptions.
Both of those games were against rookie quarterbacks Cam Newton and Christian Ponder.
Now when Gabbert faces the Packers in 2012, he will obviously no longer be a rookie, but he is still young enough to make mistakes against a wise veteran like Woodson.
Cam Newton had his first tough test against the Jaguars in Week 3, but he's still a player to look out for if you're a fan of the Jaguars.
The Jags' defense caught a bit of a break playing in the middle of a monsoon, which slowed down Newton and the Panthers.
The rest of the league was not so lucky. Newton broke rookie records, throwing and running, and he exceeded everyone's expectations of him. The next time he runs into the Jaguars, the Jags better pray for another wet, soggy day to slow him down.
This may seem like the easy, obvious answer, but Tom Brady has had some ridiculous outings against the Jaguars the last couple of seasons.
In five career games against the Jags, Brady has thrown for 1,207 yards and 13 touchdowns.
His last two games against the Jags are simply amazing, however.
In 2009, Brady completed 23 of 26 passes for 267 yards and four touchdowns. In the 2007 divisional playoffs, Brady completed 26 of 28 passes for 262 yards and three touchdowns.
Brady is good against almost every team (except the Giants in Super Bowls), but it's something about the Jaguars he loves because he doesn't even throw incomplete passes against them.
Darren McFadden has only played the Jaguars once in his short career, but it was a memorable one.
In that one game, McFadden ran for 123 yards on 23 carries and scored two touchdowns. He also caught three passes for 86 yards and another touchdown.
He had touchdowns of 51 yards (on the ground), 67 yards (through the air) and a 36-yard scamper in which he emphatically stiff-armed a Jags' defender on his way to the end zone.
Steven Jackson has played two career games against the Jaguars.
In his first game back in 2005, he had one of the best games of his career rushing for 179 yards on 21 carries and added a receiving touchdown.
Despite obscurity in St. Louis, Jackson is still one of the better backs in the league. In 2011, he amassed 1,145 yards on the ground without having consistent quarterback play.
The reigning NFL Defensive Player of the Year has only two career sacks against the Jaguars, but he's still a player that makes opposing tackles and quarterbacks shake in their cleats.
Last season, Suggs recorded 14 sacks, forced seven fumbles and even grabbed two interceptions.
Against the Jags in 2011, he recorded five tackles and one sack.
Yes, the brother of Jaguars defensive back Dawan Landry, Laron Landry is quietly making a name for himself in Washington, playing on a pretty good defense for the Redskins.
Landry is a guy that lines up in a variety of places, which could cause confusion for young quarterbacks, and he is not afraid to move up to the line of scrimmage in run support.
The Redskins have good pass rushers in Brian Orakpo and Ryan Kerrigan, but Landry is definitely a net contributor to the Redskins' defense.
The engine that makes the machine of an offense go in New Orleans is running back Darren Sproles.
Sproles was Mr. Everything for the Saints in his first season in New Orleans, as he broke the single-season all-purpose yardage record with 2,696.
When teams plan for the Saints, they have to be keenly aware of where Sproles is at all times if they have a shot at stopping them.
In his one game against the Jaguars in 2011, he gained more than 100 yards of offense.
The last time Marshawn Lynch played the Jaguars, he was a member of the Buffalo Bills and did not have much success.
But Lynch has had a resurgence in Seattle and is capable of going into "beast mode" on the Jaguars if they were to meet.
The Jaguars are pretty solid against the run, but Lynch is still a guy that the defense has to worry about.
Last season, Lynch rushed for a career-high 1,204 yards and 12 touchdowns and possibly cashed in on a Skittles endorsement deal in the process.
No, James Harrison is not the guy Jags' fans hate to see on the field.
Although he may be the scariest man to meet in a back alley, Harrison has only two career sacks against the Jaguars.
It's his partner on the other side of line, Lamarr Woodley, that has given the Jaguars fits.
In three career games against the Jaguars, including the 2007 Wild Card playoffs, Woodley has recorded six sacks, two sacks in each contest.
In 2011, in only 10 games, Woodley still managed to record nine sacks.
Andre Johnson has scorched his fair share of defenses in his day, but Jaguar fans always dread seeing the Texans coming up the next Sunday because they know that it is almost a given that he will have a big day.
In 15 career games, Johnson has caught 81 passes for 1,114 yards and five touchdowns.
Johnson was sidelined a good portion of 2011 due to hamstring problems, which hurt his numbers a lot, but Jaguars fans are too familiar with how good Johnson can be.
Another player Jaguars' fans are all too familiar with is Titans running back Chris Johnson.
Johnson hasn't consistently destroyed the Jaguars' defense, as they have held him in check a couple times. But when he does go off on the Jags, he does it in a big way.
An example of this was during his 2,000-yard season in 2009 when he rushed for 228 yards and two touchdowns on 24 carries.
Jared Allen is yet another pass rusher that would give the Jaguars' offensive line fits.
Allen came oh-so-close to breaking the single-season sack record last season with an amazing 22 sacks.
All the while having one of the worst secondaries in football.
In four career games against the Jaguars, Allen has racked up 2.5 sacks.
