Really? I will say that Farve didn't lose the game for Minnesota, but he certainly kept the Saints in it. You say he made one mistake, but that one mistake gave the Saints the opportunity to win that game. If he throws it away, or runs out of bounds, he gives his own team a chance to win.
To claim Farve has no culpability in that loss is not only wrong, but it is ludicrous.
They lose by 20 if Favre doesnt play like he did tonight. To put the blame on him shows you have the football IQ of a 2 year old.
