I think Ohio, Toledo, Central Michigan, and Bowling Green are all going to be good close games. The MAC is a lot better than in years past and I think a lot of people haven't caught up to that yet. Now don't get me wrong, I don't think any of those teams should be favored, I just don't see them getting blown out in those games. I could also see Minnesota and Georgia Tech being either close games or blow outs depending on which T Tech and which USC show up (they have both been very inconsistent). Arizona and Nevada is an odd game. I honestly have no idea what will happen in that game. Safe money says Okie St. will blow out Purdue, but Purdue just seems to be a team that just never goes away given they are the biggest underdog in Vegas (+17), I would consider betting on Purdue at those odds.
If you look at Vegas Odds, the biggest underdogs are Purdue (+17), NIU against FSU (14), Louisville (+14), Minnesota (+13), and SMU against Fresno (11.5). There are a bunch of teams that are 10 point dogs including Nebraska against Georgia, Nevada, Toledo, and Georgia Tech. The only two other games 9 or above are ND against Bama (9.5) and Kansas St. against Oregon (9).
So you have a lot of the big underdog games, but you are missing quite a few and have a couple that shouldn't be in there at all.
