2012 NFL Free Agents: Players Who Will Regret Leaving Current Team

That green-looking grass is going to quickly turn brown for a few free agents. This is not unique. It happens every year. 

Players take off to a new team with for a shiny new contract and proceed to underwhelm their new team and fanbase. 

Here are three players that will fall into that group. 

Vincent Jackson, WR, San Diego Chargers

The 29-year-old Jackson is one of the league's most productive receivers. He has gone over 1,000 yards in three of his last four seasons. 

The only season he failed to do so in that stretch was his injury/holdout-shortened 2010 campaign. He is clearly due a big payday. 

Jackson has had a rough time trying to negotiate a new deal with the Chargers, and he will find a deal he likes from another team and bolt like the symbol of his soon-to-be-former team. 

This is not going to work out well for Jackson. He is perfectly fit in San Diego's offense. He is not a receiver that runs quick routes. He likes to get deep, and the Chargers like to get him the ball deep. 

It also never hurts that Philip Rivers is the QB dropping in the dimes. Jackson is not going to get anywhere near the targets or production on another team. 

John Abraham, DE, Atlanta Falcons

Abraham has been a fantastic end. He is productive and durable. He just finished his sixth season with the Falcons. 

During that time, he tallied 58.5 sacks. He is going to get a nice payday as teams try to bolster their pass-rush. 

Steve Wyche of NFL.com relayed a message from Abraham's agent that points to the fact that early negotiations with the Falcons are not going well:

"

Rich Rosa, the agent for Atlanta Falcons defensive end John Abraham, said Wednesday that he believes his client will become a free agent this offseason, based on contract talks with the team.

"

There is going to be a team that swoops in and overpays for Abraham. The problem with this fine player is that he will be 34 at the beginning of the next season. 

His production is going to fall, and it will be well below what he is being paid to produce. That is going to make fans angry, and it will result in him being cut before his new contract expires. 

If he stays in Atlanta, the fans and the team would be quicker to excuse his diminishing results. 

Carlos Rogers, CB, San Francisco 49ers

After spending the first six years of his career with the Washington Redskins, Rogers signed a one-year deal with the 49ers last season. And his stellar play was a big surprise. 

He tripled his previous career high with six interceptions. He also put up his second highest passes defensed mark, with 18. 

That year was a huge boost to Rogers' value, and at 30 years old, he is going to look for the most lucrative contract he can find. That isn't likely to be with the 49ers. 

The problem with this for Rogers is that he is not going to be able to duplicate that success. 

This season, Rogers enjoyed the ideal position for corner. He played on a complete defense. San Francisco's front seven routinely handled the run game. This allowed the safeties to stay back an keep an eye on the deep passes. 

They also had a fierce pass-rush, which meant Rogers didn't have to spend a lot of time keeping track of his man. 

Wherever he goes, his situation will not be as ideal, and his performance will reflect that.
