QBs that make just enough plays to win close, low scoring games while playing with great defenses dont tend to replicate the "clutch" they appeared to have. Basically what youre saying is that if Sanchez performed exactly the same, but the defense was worse, then Sanchez would be performing worse since it wouldnt be just enough to win anymore. It makes no sense because a QBs performance shouldnt be seen through the success of a defense.
our D has been pretty close to 2010 so why have we dropped off so much if that is the case? People bashing Sanchez act like our D was the '85 Bears. Our Ds were good and at times very good but never great so how can you win w/ a non great D and bad QB?
