Guess the Big East/American was/is the best conference in the nation with a winning record over the SEC...
I think the ACC and SEC are really the main conferences that go head to head. Pac12/Big10 don't constantly play games against them so they don't have stats to show them being dominated more.
Look at pac12 vs ACC. Its not like their matching up against good times. UVA has played UCLA and Oregon in the past couple of years and lost but UVA is near the bottom of the ACC. That's a bit of a mismatch, but Oregon vs Mich St. is more top vs top. I wish teams of relative strengths inside their own conferences would match up more often. Beating up on the bottom of opposing conferences is kinda pointless.
