1. We've been saying it for a few years now but quarterbacks eventually hit that 'wall.' And when they do it seems to happen overnight. I was as surprised at anyone that Brady not only made it through the season but was fairly efficient. I don't think that happens again.
2. Bucs had the luck that teams need during a Superbowl run. As we saw in 2010, it doesn't happen twice in a row.
3. Speaking of twice in a row, it is really hard to repeat in this league. The Chiefs did it because they have a phenomenally-talented QB, but with a target now on their backs I don't see the Bucs making it all the way again.
