Every week in the NFL season there will be starters that lose their jobs.
The reasons can be a long list, but you have everything from poor performance to injury, coach's decision, suspension, being outplayed by your backup, getting waived, personal reasons, and being declared inactive.
For Week 2 of the 2010 NFL season, there were a number of players that may have just played their way out of a starting job or already learned that they lost their starting jobs from Week 1.
The poster boy for this week is Oakland Raiders quarterback Jason Campbell.
For more details, check out the slideshow.
The Oakland Raiders were a dark horse pick to win the AFC West division this season.
Starting QB Jason Campbell began his Raiders tenure with a season-opening loss to Tennessee. He followed that up with a half of football to forget.
Campbell completed eight of 15 passes for 87 yards and threw one interception, no touchdowns, and led his team to three points for the entire first half.
When you realize that Campbell was playing against the St. Louis Rams, then you know he was pretty bad.
At halftime, Campbell was benched for Bruce Gradkowski, who promptly led the Raiders to a comeback victory over the Rams. It would be a surprise after his benching if Campbell starts the Week 3 contest, but stranger things have happened.
The Washington Redskins defense was absolutely torched by Matt Schaub and the Houston Texans to the tune of 497 passing yards allowed. I realize the game went into overtime, but seriously, 497 yards?
Schaub hit on 38 of 52 passes, finding at least eight different receivers. Seven Texans had at least one catch for a minimum of 15 yards, and five Texans had at least one catch for 20 yards.
The biggest Redskins killers were Andre Johnson and Kevin Walter, as both receivers had at least 10 catches and over 140 yards in receptions.
The worst part about all of the above was two things. Schaub faced pressure since he was sacked five times. The other thing was that this performance was done in a home game, something Redskins fans will not soon forget.
Wonder who Daniel Snyder can possibly sign to a free agent contract to play some pass defense?
Giving up 497 yards to an elite passer like Matt Schaub in his prime is one thing. But despite having their offense move the ball up and down the field, the Houston Texans defensive secondary was burned by old man Donovan McNabb for 426 passing yards on Sunday.
McNabb completed 28 of 38 passes and also hit eight different receivers. Santana Moss led all Redskins receivers with 10 catches for 89 yards, but his longest was only 13 yards
There were at least six other Redskins receivers that had a catch of 20 yards or more. Even ancient Joey Galloway had three catches for 88 yards.
It wouldn't be difficult to envision some starters losing their jobs over Sunday's game for both of the secondaries involved.
Clinton Portis had two rushing touchdowns Sunday, each from one yard out. You are thinking that is pretty good.
Then you look at the rest of his day: 13 carries for 33 yards in total, and that is counting his longest run of 12 yards. So the other 12 carries went for 21 yards.
If that average does not overwhelm you, consider that the Houston Texans defense was playing back on their heels, as they were being torched for 426 passing yards by Donovan McNabb. Playing in front of the home crowd, Portis had trouble getting his ground game going.
His replacement, of course, would be former All-Pro Larry Johnson, who on the day managed to have two rushes, one for three yards and one for minus-10 yards.
While the Raiders had the guts to make a move at QB to pull out their first win, the Buffalo Bills have stuck with Trent Edwards for the full game in each of the first two weeks.
The result was one touchdown drive in each game, three sacks in Week 1, and four sacks in Week 2.
Edwards has trouble sensing pressure, which is a problem when you are standing behind the Bills' current offensive line. When he does have the time to throw, he gets happy feet and starts rolling out of the pocket when there is no need to.
Edwards completed 11 of 18 passes for 102 yards on the day. He was credited with two interceptions, although anyone watching the game knows that neither one was his fault.
Since Chan Gailey is a new head coach with the Bills, he has decided to give Trent Edwards a long rope to start out the season. I just hope Gailey doesn't hang himself with the extra length. I expect the leash to get tighter starting in Week 3, and it wouldn't surprise me to see either Ryan Fitzpatrick or Brian Brohm before the month is over.
Cornell Green was signed in the offseason to provide some veteran leadership and a presence on the young Bills offensive line.
Having watched Cornell for the first two games, it is very clear that he no longer is athletic enough to keep up with younger and faster defensive linemen or linebackers.
Getting routinely beaten and having a quarterback in Trent Edwards that has suffered concussions in two straight seasons is basically what you would call a recipe for disaster.
As one of the Bills' Featured Columnists on Bleacher Report, I would be in favor of the Bills starting any of Jamon Meredith, Kraig Urbik, or Ed Wang when he returns from his broken thumb. Let these young guys get some experience because Green will leave the Bills QB black and blue.
One of the casualties of losing his starting job in Week 2 was Bills running back C.J. Spiller, which completes the trifecta for Buffalo.
Spiller was the opening day starter for opening week against Miami, as he was given the nod over thousand-yard rushers Marshawn Lynch and Fred Jackson, even though both were healthy and able to play.
Against Green Bay, the Bills started Marshawn Lynch. Spiller's role was reduced to being a third down back specialist and kickoff returner. He caught some passes on screens and swing passes and had one rush for three yards.
After the game, Chan Gailey said that the Bills will ease Spiller back into the workload in the future. So much for the potential Rookie of the Year hype.
Carolina Panthers QB Matt Moore was in the driver's seat after longtime QB Jake Delhomme left for the Cleveland Browns in the offseason.
Coming out of the gate, Moore has managed two touchdowns in two games, to go along with six turnovers and two losses.
The Panthers saw enough and pulled Moore for Jimmy Clausen in the fourth quarter of today's game. What made matters worse was that the Panthers were playing at home and were up against the lowly Tampa Bay Bucs. For the day, Moore went 6-of-16 for 125 yards.
Moore picked a bad time to turn in another bad start, and Panthers fans were happy to see what Clausen could do. Maybe there will be another rookie starting NFL quarterback when we hit Week 3.
Ah yes, a trip around the NFL wouldn't be complete without a visit to see how America's Team is doing.
The winless Dallas Cowboys, off to an 0-2 start, saw their starting running back Marion Barber turn in a day to be forgotten. Barber was handed the rock 11 times but only managed to pick up 31 yards, which equals a low 2.8 average yards per rush.
Barber failed to catch a pass in the game, which is a little odd since Tony Romo passed for 374 yards. With all of that passing, the Bears defense was playing back to respect the passing game, meaning Barber should have been able to take advantage of the situation.
It didn't help that his probable successor Felix Jones was only able to pick up seven yards on seven carries.
Safe to say that the Cowboys' running game has some major problems. Cowboys owner Jerry Jones said after the game, "I'm mad, I'm upset, I'm very frustrated and extremely disappointed."
Meanwhile, in some deserted patch of jungle in Nicaragua, ex-coach Jimmy Johnson continues to throw up in the bushes. Not sure if his stomach is upset over the Cowboys' running game or not.
Jets cornerback Darrelle Revis appeared to hurt his leg against the New England Patriots on Sunday. The shutdown corner aggravated a hamstring injury and sat out the entire second half of the game.
No word yet if he will be missing next week and, if he tore the hamstring, how long he would be out.
Perhaps the hamstring was weak due to the size of his wallet. Sorry Jets fans—bad joke, I know.
Pittsburgh Steelers starting QB Dennis Dixon suffered a knee injury against Tennessee on Sunday and will be out while the team waits for further tests to determine how bad the knee injury is.
In his place came veteran Charlie Batch. Neither QB did much in the game, but then again, they didn't have to since the Steelers defense created seven turnovers against the Titans.
Batch's reign will be short-lived since Big Ben Roethlisberger will be back for Week 5.
Denver Broncos cornerback Champ Bailey suffered a high ankle sprain on Sunday and was forced to walk around on crutches following the game.
It is already thought that it is doubtful Bailey will be ready for Week 3, so no word yet on how many games Bailey will miss besides that one.
Another injury from Week 2 that could conceivably cost a starter his job is Chargers running back Ryan Mathews.
Mathews suffered an ankle injury and was replaced by Mike Tolbert. No word yet if Mathews will be ready for Week 3, so stay tuned.
Some other performances from Week 2 that were less than stellar:
Fred Taylor: Patriots running back had five rushes for 11 yards.
David Garrard: Jaguars QB threw for four interceptions.
Vince Young and Kerry Collins (and rest of Tennessee Titans): committed seven turnovers vs. Steelers.
One thing to count on for sure is that in every week of the NFL season, there will be some changes. Some of the changes are minor, and some are major, but you have to pay attention every week to know what is happening.
