Every year, NFL rookies have great seasons and suddenly become the cream of the crop at their position.
However, this isn't always the case, as many rookies also have disappointing first seasons with their respective teams.
Names like Ryan Leaf and JaMarcus Russell come to mind when you think of the biggest rookie disappointments in the last 20 years.
Here is this year's version of the most disappointing rookie on every NFL team through the first 14 weeks.
Coming into the '11 NFL Draft, Ryan Williams was one of the top RB prospects available.
While has was at Virginia Tech, he rushed for over 1,600 yards and 21 touchdowns in his freshman season for the Hokies.
Unfortunately, he was never able to get it going in his first year in the league.
He ruptured his patella tendon during the preseason, which prematurely ended his rookie season.
Rodgers was a highly-explosive back coming out of Oregon State.
During his time there, he rushed for nearly 3,900 yards and 46 touchdowns for the Beavers.
The Falcons decided to take him in the fifth round of this year's draft, only to see him struggle for only 172 rushing yards in his rookie campaign.
Even though he has been disappointing, it's still too early to tell if he can be the back to complement Pro Bowl RB Michael Turner in the future.
The Ravens' wideout has failed to do anything in his first season in the league.
Doss has zero catches on the year and has only seen action in less than a handful of games.
He will need to do better than this if he wants to stick around in Baltimore for the long-term.
Defensive back Aaron Williams has been a big disappointment for the Bills this season.
He has been beat badly way too many times in coverage, including on the play above.
He also just doesn't seem to have what it takes to get it done as a cornerback in the National Football League.
Fua has failed to impress hardly anyone in his inaugural season in the league.
He's registered just nine tackles in 11 starts and doesn't get the consistent push from the DT position that the Panthers had hoped for when they drafted him.
At they very least, he will have some mistakes to learn from in the future.
Carimi was supposed to come right in and start at the right tackle position for the Bears this season.
After starting the first two games of the season, the former Wisconsin Badger suffered a season-ending knee injury during Week 2.
The Bears hope that he will fully recover and come back next season as their RT of the future.
This pick was a no-brainer for me.
The third-round pick out of Nevada has yet to see the field for the Bengals this season.
This is a shocker, considering that Moch won WAC Defensive Player of the Year honors while playing for the Wolfpack.
Fourth-round pick Jordan Cameron has struggled to put up any numbers this season.
He has one measly catch for seven yards during the entire year.
It's way too early to call him a bust, but Cameron sure hasn't convinced anyone that he will be a solid TE, either.
Here is yet another rookie who received a decent amount of hype going into this year's draft.
In his case, he hasn't lived up to any of it yet.
The Cowboys' rookie has just five tackles and a pass deflection in seven games from his inside linebacker position this season.
Moore was drafted by the Broncos in the second round to help shore up some issues at the safety position.
So far, he has yet to shore up many of these problems.
The Los Angeles product has been a liability in pass coverage and has just one pass deflection in six starts this season.
When you think about some of the most-hyped prospects of this year's rookie class, the name Nick Fairley has to cross your mind.
Unfortunately for Fairley and the Lions, his name might belong on the most over-hyped list as well.
The former Auburn star has only registered nine tackles and a sack this year, while battling a foot injury all season.
Anytime a running back scores 18 touchdowns in a season for any D-1 level program, you would expect some kind of an impact in his first season in the NFL.
That hasn't been the case for Packers' rookie Alex Green so far this season.
The former Benson Polytechnic High star has had only three carries for 11 yards in a RB-by-committee system in Green Bay.
This name, like many others on this list, might not be very familiar to most who read this article.
However, the Texans are very familiar with him.
He was their second-round pick back in April and has really struggled in their secondary.
Indy's Chris Rucker is a rookie that hasn't really been talked about too much this year.
The Colts' cornerback has had some good moments in his rookie season, but also some bad (see above picture).
He's notched 18 tackles in limited playing time but has not been very solid in coverage overall.
Gabbert was drafted No. 10 overall in 2011, the first QB taken after Heisman trophy-winner Cam Newton and Jake Locker.
Through 13 games this season, he has hardly earned his top-10 pick status.
The former Mizzou star has thrown only 10 touchdowns and completed just 50 percent of his passes so far.
Worst of all, he doesn't look comfortable in the pocket at times and looks very gun-shy when it comes to throwing the ball downfield for the Jags offense.
Brown has really struggled on special teams and in the Chiefs secondary this season.
He has been flagged multiple times in both areas and has been beaten in coverage many times as well.
The team had high hopes for the former University of Colorado star, but he has failed to live up to these as of yet.
He will need to step up it up in these last three weeks or he might have a difficult time seeing the field next season.
The second of two seventh-round picks for the Dolphins in last April's draft has really struggled to get it going in his rookie season.
The San Diego product has played in 13 games but still hasn't really made much of an impact for the Miami defense.
He has been the weak link in the Dolphins' secondary all season and continues to get burned in coverage each time that he is in the game.
You can't always expect a lot out of any seventh-round pick, but the Dolphins were likely hoping for more than they have received from Wilson so far this season.
Defensive tackle Christian Ballard was a big-time talent coming out of the University of Iowa.
He was likely going to be a first-round pick but dropped down to the third round after some drug problems.
The Vikings picked him there in hopes that they got a steal.
He has returned the favor by recording just 10 tackles in 13 games this season.
Vereen was one of the best running backs in this year's rookie class.
Don't tell the Pats that, or that might not believe you as of yet.
To say that the former Cal Bear has struggled in '11 would be a major understatement.
He has seen action in only five games, with only 57 yards and a touchdown to show for it.
When the Saints took the former University of California DE with the 24th overall pick in April's draft, they were hoping to get another pass-rushing treat on their defensive line.
Instead, they got a player that still looks like he doesn't belong in the NFL as of yet.
In 13 games this season, Jordan only has 25 tackles and four pass deflections for New Orleans.
Worst of all, he still hasn't registered a sack, which was why he was drafted by the Saints in the first place.
Marvin Austin is just another player on this list that has lost his rookie season due to injury.
In training camp, Austin tore his pectoral, which effectively put him on the IR and ended his season immediately.
It's not clear how much this setback will affect the former North Carolina Tar Heel going forward, but because of his unexpected injury, he has been a disappointment for the Giants this year.
Last April, the Jets thought that they were getting a player that would make an immediate impact in first-round pick Muhammad Wilkerson.
After all, he did record 10 sacks in his last year at Temple.
Through the first 13 weeks, he has only managed to produce one sack for the Jets defense.
Van Dyke was another player picked by the Raiders in this year's draft that had all-world speed.
Unfortunately, that's about all he has, it appears.
He fails to take solid angles in coverage and is not quite as explosive as his 4.28 40-meter time would seem.
The former Temple Owl has done nothing this year for the Eagles to justify his second-round pick status.
The rookie has made just one start, picked up 11 tackles and has been beaten in coverage in a variety of different ways.
In a year where the Eagles defense has struggled all the way around, Jarrett's performance this season has only made things worse for this unit.
Former Ohio State Buckeye Cameron Heyward was supposed to be a can't-miss talent in last April's draft.
The Steelers thought so, as they drafted him No. 31 overall.
So far, he is barely first-round worthy.
Heyward has just eight tackles and a sack this season playing at defensive end.
When the Chargers drafted former University of Michigan linebacker Jonas Mouton, they expected big things out of him in his rookie campaign.
Instead, they just got another player to add to the IR list for the season.
Mouton was placed there during Week 3 after suffering a shoulder injury.
This was a very tough choice for me.
What made it so tough was that many of the 49ers' rookie draft class has performed well this season.
Holcomb was one of the only players who has been a disappointment, due to a season-ending Achilles injury back in July.
The Seahawks guard has easily had the wildest year out of any rookie on this entire list.
First, he started out the season on a good note, playing in the first nine games of the year for the Seahawks.
Then, he became a disappointment after that.
After getting placed on injured reserve during Week 10, Moffitt was recently suspended for four games after violating the league's banned substance policy.
Greg Salas isn't on this list because he has a disappointing season from a statistical standpoint.
However, he has been disappointment based on what he is really capable of as a rookie in this league.
While at the University of Hawaii, Salas broke all kinds of records last year with 119 receptions for an amazing 1,889 yards.
You would think with that level of production at the collegiate level that he would have made more of an impact in the Rams' passing game than he has this season.
Bowers dropped to the second round of this year's draft because of medical concerns.
However, after the way he has played so far this year, it's a wonder that he was even a high-round pick in the first place.
The Bucs rookie has just 21 total tackles and 1.5 sacks all season.
For a guy that was brought in for his ability to produce sacks, he has yet to produce very much in that area.
Harper is one of three former Clemson Tigers that made the cut for this list.
He hasn't done anything this year for the Titans' ground game, rushing for just 16 yards on seven carries.
Although he doesn't get to touch the ball much, playing behind Pro Bowl RB Chris Johnson, you would have expected more out of him than what he has done so far this season.
Da'Quan Bowers' old teammate at Clemson makes this list as well, except for the Redskins.
It may be unfair to judge too many defensive linemen in their first season in the league, but Jenkins was selected in the second round by Washington to fill a need, and he simply hasn't done it.
This is due to the fact that he has missed the entire season to a torn ACL that he suffered back in the preseason.
He's just another rookie on the long list of first-year players that have been lost to injury for this entire season.
