No, not excuses. If you were more familiar with me and my positions, I object to assuming that QBs are the reason that teams win or lose. I reject the notion that Tebow won 6 games in a row for us when he played like garbage for the 1st 58 minutes in all but 1 of those games, while our D played outstanding football of opening KO to final gun to keep the score close enough to make "Tebowtime" possible. So, not only do I not let QBs steal credit from Ds for wins that the Ds deserve the credit for, but I also don't blame QBs for loses in which their Ds failed them.
Of course, whenever I do, people claim they never said. Except you just did.
