Both the Ohio State Buckeyes and Michigan State Spartans are obviously locks to make the 2012 NCAA Tournament, but Sunday's Big Ten Championship between the two teams still could have major ramifications on this year's tournament bracket. If the Spartans win, it would be hard to imagine them not getting a No. 1 seed after also winning a share of the regular season conference championship. But if the Buckeyes are victorious, they would have a claim to a top seed as well, though it's more likely that both teams would end up as No. 2 seeds.
