Charley Casserly has raised doubt over the probability of Michael Vick lasting a full season at the heart of the Philadelphia Eagles offence.
The 33-year-old quarterback produced a stunning first-half display against the Washington Redskins on Monday night, with five scoring drives at an average of one minute, 44 seconds.
However, the number one pick from the 2001 NFL draft appeared to struggle with the pace and intensity in the second-half, and was seen to be limping after a couple of hits.
Casserly, a former NFL General Manager who worked with both the ‘Skins and the Houston Texans, believes this is a sign of things to come, and doubts whether the former Atlanta Falcon can cope with the pace set by head coach Chip Kelly.
"We saw Vick limping around. Vick's not gonna last. He's running the ball in this offence, he's not just handing it off," said Casserly on NFL Network's ‘Around the League Live’.
London Fletcher also weighed into the debate about the Eagles offence, with the Redskins linebacker believing it will be difficult for a 53-man team to maintain such a pace throughout the season.
However, the 38-year-old revealed afterwards that it was "the longest first quarter of my life", suggesting that if Philadelphia can maintain such a rapid offence, they’ll be on to a winner.
"One of the things that I was concerned about running this type of offence in the National Football League -- in college, you have so many players," Fletcher said.
"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?
"I just hope there's not too many other offences coming into the league like the Philadelphia Eagles(or) I'm gonna run out of this league pretty soon."
Vick hasn’t played all 16 regular season games since 2006, and back-up Nick Foles may well need to be ready for when the time comes to give the starting QB a rest. The Eagles have to wait until week 12 for their bye.
