Well I don't know what he said about McNabb, although I definately don't think he is the best QB in the NFL. What do you base that on? I mean, you've got QB's that run better (Vick), throw more TD's (Manning), win championships (Brady).
If he wins Sunday, then you have a case to base your opinion. If not, he'll rank about #5 as far as QB's go. If he wins, I'll move him up to #3 still behind Brady and Manning.
