McNabb looks very much like QB in decline - NFL - Yahoo! Sports
I believe the system DID help him a lot in Philly. Yes, he had athletic talent earlier in his career. He could run well and had a strong arm on long throws. Accuracy never impressed anyone and it appears that last year exposed his inability to adapt or learn...unless it was a case of a lack of effort.
Minnesota is supposed to be a system that fits his skills. Week 1 was a disaster but I won't judge his whole season on one horrible week. However, I do think that he's done. Injuries have really taken a toll on him and his lack of accuracy is really showing now that his arm and scrambling ability are declining.
Many mediocre QBs have done adequate jobs in Reid's offense. This is why I am not buying into Kolb. He didn't impress me in Philly and I don't expect him to excel anywhere else.
Koy Detmer, Jeff Garcia, Ty Detmer, AJ Feeley...all have looked at least serviceable in Philly.
