The Philadelphia Eagles' new offense dazzled fans and exhausted Redskins defenders on Monday night when it debuted.  While the quick, no-huddle offense was impressive, some doubt if Michael Vick can remain healthy for the entire season playing at that pace, NFL.com reports.

NFL Media's Charley Casserly, a former NFL general manager, doubted if Vick could last a full season in Kelly's "frenetic" offense.

"We saw Vick limping around.  Vick's not gonna last," Casserly said on Tuesday during an NFL Network interview, via NFL.com.  "He's running the ball in this offense, he's not just handing it off."

Vick completed 15-of-25 passes for 203 yards and two touchdowns, adding 54 yards on the ground with one touchdown on nine carries.  The 33-year-old's first five scoring drives took an average of 1 minute and 44 seconds, according to NFL.com, but Vick was kept to just nine yards of passing in the second half.

He also appeared to get injured early in the fourth quarter during a 36-yard scramble.  Vick was seen limping after the play, and he appeared to walk with a slight limp after the game.

The durability of Vick has always been a concern.  He's missed 12 games over the last three seasons, and he's only once played in all 16 games of a season.

Redskins veteran London Fletcher, who witnessed the Eagles offense firsthand, thinks the Eagles' new style of play is impractical given the size of team rosters.

"One of the things that I was concerned about running this type of offense in the National Football League - in college, you have so many players," Fletcher said, via NFL.com.  "You have over 100 players on your football team, but in the National Football League, you only have 53 players.  ... Will they be able to sustain this type of pace?"
