Someone has to lose the #1 Ohio State - #2 Michigan game on Saturday. Odds are on Ohio State by 7, which would leave Michigan likely to drop in the rankings.
If #3 USC beats #17 Cal (as they are favored to do by 6), USC would likely move up to #2 and be in the national championship again this year.
I'll pick Ohio State by 10 and USC by 10.
In the NFL, Houston is favored by 2 over Buffalo, but with the Bills recent near-upset of the Colts, I'll pick the Bills by 3.
New England is favored by 6 over Green Bay. Looking carefully at the stats, they are a surprisingly well-matched pair of teams, but I think the Pats will win easily.
