The offseason is here and now the Eagles look to see what they need to do to build upon last season's surprising NFC East Championship run and on Wednesday the Eagles locked up one of their own.

The Eagles announced that they had agreed to a new deal with All Pro left tackle Jason Peters on a 5-year contract through the 2018 season. The deal is reportedly worth $51.3 million with $19.55 million guaranteed according to ESPN's Adam Schefter.

Peters contract was up at the end of the upcoming 2014 season and at the age of 32 he is still playing at a high level despite tearing his achillies twice in less than a year starting all 16 games in 2013. With free agency just a few weeks away the Eagles brass felt that their left tackle was a priority to keep around for years to come.

“Jason is everything you look for in a left tackle,” said Eagles general manager Howie Roseman. “The unique blend of size, speed and athleticism that Jason possesses is something that everyone wants in an offensive lineman. However, what really makes him unique is his desire to improve day in and day out despite the fact that he’s played at an elite level for so many years. We are truly rewarding Jason’s excellence, as he’s a guy who has made six Pro Bowl appearances and has been selected an All-Pro five times. We’re excited to be able to keep him in Philadelphia for years to come.”

The 6'4" 328lbs tackle considered by many the best left tackle in the game is entering his 5th season in the City of Brotherly Love being named to the Pro Bowl four times and twice as a NFL 1st team All Pro including last season. The Eagles also drafted tackle Lane Johnson in the 1st round with the uncertainty of how Peters was going to return from a major injury to eventually be the heir to the left side of th line. But with this long term deal and the guaranteed money of almost $20 million the Eagles have the faith that he will continue to deliver for the long term future and they have their bookend on the offensive line keeping Johnson on the right side as the Bird's might have the best offfensive line in the NFL today.

With this deal, that leaves only starting C Jason Kelce without a long term deal as it seems that it's a focal point for management to keep this unit that helped block the way for the NFL's leading rusher, Lesean McCoy intact. And by Peter's agreeing to this deal, the structure of the contract hasn't been released but with the Birds only at about $10 million to work with this offseason I'm sure it helped open up cap space for the Birds to work with this offseason to bring in some key pieces they need to help make a run in 2014.
