Michael Vick has added nine pounds of muscle so far this offseason.

Vick is very aware that his inability to stay on the field has crippled the Eagles of late. He's missed 11 games due to injury over the last three seasons and was limited in a fistful of others. New coach Chip Kelly has a new training regimen, and Vick's upper body is visibly bigger. The last time he played in all 16 games was 2006 -- the year before his prison stint.

Asked by ESPN's Sal Paolantonio to describe new Eagles coach Chip Kelly's offense, Michael Vick called it "refreshing," "very innovative," and unlike any offense he's played in before.

Vick has completed two practices in the fast-paced scheme. "It's great, it's awesome," he said. "It's nothing (like) I've ever seen before as an offense. It's very refreshing, it's very innovative. And we do a lot of things that just put the ball into guys' hands and allow them to go out and make plays and play free. ... It's been an awesome two days and we've gotta continue to work hard."

Michael Vick and Nick Foles split first-team reps on the first day of Eagles' voluntary workouts Tuesday.

Let the "competition" begin. Coach Chip Kelly insists his two QBs are on an "even" playing field. "There wasn't one set guy that just went with the ones the entire day," Kelly said. Kelly comes from the "competition at every position" school of coaching, but everything from Vick's salary to his skill-set suggests he's the heavy favorite to be under center in Week 1.
