While the NFL often rewards the best players with the best paychecks, this is not always true.
Much of the time, some of a team's most important players are very underpaid, while big-name players who make the most money often don't deserve it.
The Eagles are definitely that kind of team.
The team is loaded with Pro-Bowlers but often gets the most production out of its unheralded stars.
No team is perfect, and the Eagles are no exception. These four players are either underpaid or overpaid by the front office based on their production and overall importance to the team.
Mathis, with a contract of $25 million, isn't exactly poor.
But, Mathis is the team's best offensive lineman. He was a big part of the reason why LeSean McCoy had the breakout year he did.
While Mathis has a good contract, he does not have the contract of a dominant offensive lineman. Jason Peters, for example, had a contract of six years and $60 million when he was first signed by the Eagles.
Peters also does not protect Michael Vick's blindside, as Vick is left-handed.
Mathis is paid well, but likely could have made more had he joined another team.
While critics may say that Maclin failed to step up in clutch situations this past season, no one can dispute that he is a vital part of the offense. One could also argue that Maclin is just as valuable as DeSean Jackson.
Maclin may not have Jackson's speed, but he is still faster than most players in this league. He combines that speed with great hands and an ability to go over the middle.
Jackson lacks his physicality and strength and Jason Avant lacks his speed.
Maclin amassed 10 touchdowns in 2010. In 2011, his numbers fell slightly, but he was also recovering from a serious summer illness during a shortened offseason.
Having a player like Maclin is absolutely necessary to stretch the field for Jackson and make the Eagles' offense thrive.
Nnamdi Asomugha may have suffered from being played out of position, but he is overpaid nonetheless.
While he is clearly a press corner, Asomugha has shown that he lacks the overall instincts and awareness that Darrelle Revis possesses—and that he is not as elite of a corner as many expected.
Furthermore, Asomugha often showed poor tackling and, even when he was moved back to press coverage, he gave up big plays and committed many penalties.
Asomugha also has offered little in the form of leadership, despite being a veteran player. Asomugha may bounce back and have another Pro-Bowl year in 2012, but it is clear he is not the dominant player many thought he was.
By including Vick on this list, the point is not that Vick is not a good quarterback. He very likely will have a bounce-back season in 2012 and cut down on the turnovers.
However, Vick is not a quarterback who is worth $100 million and $40 million guaranteed.
Not only did Vick commit costly turnovers in 2011, he also proved himself to be very injury-prone. Furthermore, it is clear that NFL teams have figured out how to game plan against him.
While Vick is still a good player, he likely will not return to his 2010 MVP-worthy performance.
Vick has the potential to be a franchise player, but will never be worth $100 million.
