Eagles, Jason Peters agree to extension

Matthew Emmons-USA TODAY Sports

Philadelphia has locked up its Pro Bowl left tackle for the foreseeable future and created cap space.

The Philadelphia Eagles and offensive tackle Jason Peters have agreed to a four-year, $41.3 million contract extension with $19.55 guaranteed, according to Geoff Mosher of CSN Philly.

Peters was scheduled to become a free agent after the 2014 season. Many people expected him to leave, considering the team drafted Lane Johnson out of Oklahoma fourth overall in the 2013 NFL Draft. However, it appears Johnson will be staying on the right side for a while while Nick Foles keeps Peters as his blindside protector.

The deal will keep Peters in Philadelphia until he is 36 years old, should he play out the entire deal. The new contract also helps the Eagles, who keep a two-time All-Pro and create some cap space for the upcoming offseason, in which they have key free agents such as Riley Cooper and Jeremy Maclin.

Under Chip Kelly, Philadelphia rebounded following a mediocre start of the season to go 10-6 and win the NFC East. In the playoffs, the Eagles fell on a last-second field goal to the New Orleans Saints in the Wild Card round. Still, the campaign was a success and much of it can be contributed to their offensive line play.

Philadelphia has one of the best lines in the game with Peters and Johnson manning the left and right tackle spots, respectively. Inside, Evan Mathis is arguably the best guard in football, an argument Pro Football Focus would make. Mathis graded out as the best guard in the league by a wide margin, mostly due to his run blocking.

Mathis, 32, was given a 40.2 run blocking grade, with the next-best grade coming in at 19.7. By the way, that grade belongs to the Eagles' right guard, Todd Herremans. Mathis made his first Pro Bowl and All-Pro teams in 2013.

At center, Jason Kelce, 26, has become one of the most reliable men at his position. He too is rated the top player at his spot by PFF, garnering a grade of 18.9.

Not surprisingly, the Eagles had the top rushing attack in the NFL with 160.4 yards per game.
