IIRC, it's not the seeding that is the problem, it's the draw. Last year was actually somewhat fortunate, and that team deserved a 2 seed. Yet the year before they got Kentucky as a 4 seed while being the overall #1. Kentucky as a 4 was enough of a joke, but putting them in the overall #1 seed's bracket was a slap in the face. I suppose the year before that getting the worst #2 seed kind of sucked, but they deserved a 2. The bracket worked out in OSU's favor with Kansas and GTown going down early, but then of course they lost to Tennessee.
I suppose in 08 and 09 they could have gotten a better seed or actually in the tournament, but in 06 and 07 they got good seeds.
