Last weekend, we saw several favorites fall in college football. West Virginia defeated a favored Maryland team in Maryland. Utah beat BYU. Notre Dame actually won a game and it came against a ranked opponent (no, I don't care that Notre Dame was favored, it was still shocking).
This weekend we can expect more of the same. While professional football thrives on parity, college football thrives on the upset. There will be no team that comes from the depths of the Sun Belt Conference to play in the BCS National Championship, but it is nice to know that on any given Saturday the Sun Belt could whup the SEC.
These are five teams that enter the weekend as favorites but could leave on the other side of the weekend with a loss. These five teams need to take notice...now.
