These days I don't care too much one way or the other for Favre either, but I agree that his last pick wasn't the main reason for the loss. Yeah, timing of the mistakes is huge, and the timing of that pick was bad. But the only reason he's throwing the ball at all is because of 12 men in the huddle. That is actually a screw up equal to the pick because it put them into a pass play, which they wouldn't have done otherwise.
I also agree that the fumbles cost them more as well (in the overall scheme of things). And RWS, don't bother taking Saban out of your mouth to imply I'm sucking Favre....again, I don't care one way or the other, it's just my opinion on the game.
