The Big 10 has a really tough bowl schedule, I would say the hardest out of every conference. What people always fail to look at when comparing bowl records is the matchups. I can see the SEC doing well this bowl season, but that's because for the most part they got a VERY easy schedule. Bama got the worst team in the BCS games, Georgia got Mich St instead of Ohio St, Kentucky got an overrated ECU team, South Carolina did draw a pretty tough Iowa team that should beat them, LSU drew a much less talented team in GT (they'll still lose because of the coaching difference) and so on..People always state bowl records to prove one conf is better than the other but never really look at the fact that maybe some conferences had it tougher.
Big 10 will do well ATS imo, and so will the Pac 10. Not going to argue that they're great conferences, but both will do well ATS this bowl season.
