I think there's is an "East Coast" (namely ESPN) bias against the Big 10 and Ohio State.
The "East Coast Bias" is actually in favor of the Big 10. There have been many times, especially through the 90s, when lesser-deserving Big 10 teams were getting a lot of publicity over other teams.
1994 and 1997 in particular come to mind, when both PSU and Michigan got a lot of air time, and Michigan ended up with half a title they didn't deserve, all because of that bias. It all stems from the fact that most of the football-covering media used to be centered in the Northeast, although that is changing now. ESPN in particular used to shill for the Big 10, but they've now switched their love to the $EC.
