2011 NFL Free Agency: 4 Most Regrettable Moves

Now that the NFL free agency dust has settled, every team has had its major signing and then some; however, some NFL teams have made some signings that are regrettable. Either the terms of the contract are terrible, or the player who was signed may not be poised for any sort of production whatsoever.

Some players are old, others young and overpaid, while other signings make little sense for the team's needs. Regardless, there are signings that teams will wish they never made in the very near future.

Here are five of the most regrettable free agent signings this summer.

Philadelphia Eagles: Ronnie Brown

The Philadelphia Eagles went on a signing rampage this summer and for good reason—the team has a superstar in his prime in Michael Vick, and the team was considered elite and were Super Bowl favorites entering the 2011 NFL playoffs. 

And while most of these signings were great (which includes Nnamdi Asomugha and Cullen Jenkins), others weren't so great. 

The worst free agent signing? Former Miami Dolphins RB Ronnie Brown, who's 28, injury prone and hasn't produced big numbers for the Dolphins since 2008, the first year the 'Fins used the Wildcat formation. 

Brown has had his setbacks, but his vision has never really developed at the level you'd like to see from a 28-year-old back. He's not that great at reading the shifting in the offensive line, and while he's a big, fast running back, he'll often run straight into the arms of waiting linebackers. The Dolphins didn't re-sign him for a reason.

The Eagles won't use Brown as a feature back—that's what they have LeSean McCoy for—but he might not be worth signing as a second option at RB. His stats largely benefited from an underrated Dolphins offensive line and the presence of Ricky Williams (which, ironically, should hurt his stats).

New York Jets: Plaxico Burress

Plaxico Burress was in jail for the past 18 months, so it's a wonder why anyone would sign Burress. 

But the New York Jets? Are you kidding? 

The Jets already have enough, er, "colorful" characters, and adding another would be hell if it fails. The entire team's chemistry could be ruined for a player that may or may not be in football-ready shape. 

The mental stability for your average NFL athlete might not be there for Burress, either. Michael Vick took quite a while to get acclimated to the Eagles system, and that could be because of having regret for doing what he did. Either way, Burress is going to need a lot of time to get used to all things football-related. How much time that'll take (if it happens) is anyone's guess.

Philadelphia Eagles: Vince Young

Whenever any team decides to go on a signing rampage and makes some really awesome signings, the chances that they have multiple horrible signings skyrockets. 

That's the case with the Philadelphia Eagles, who signed Vince Young, the loudmouth who said the Eagles were the NFL's "Dream Team."

Young may be an OK quarterback, but he's definitely not worth the mental instability. Michael Vick is already in Philadelphia; do the Eagles need another possible distraction if Young doesn't get what he thinks he deserved?

Carolina Panthers: DeAngelo Williams

(Note: Re-signings are fair game.)

DeAngelo Williams is a 28-year old running back, and while backs at those age still have a tiny bit left in the tank, they're on the downside of their career, and that's never something you want to have on your team. 

The worst part? Williams signed a five-year, $43 million contract, with $21 million guaranteed. 

That's terribly stupid. 

Running backs have short shelf-lives and they're easily replaceable. Sure, Williams could be hard to replace, but with other, younger RBs waiting in the wing, they might have found a gem.
