Ohio State is WAY overrated. They have lost to all three good teams they have played, and squeak out wins against poor ones.
They lost at UNC by 8, got ripped and shredded at Florida, and lost at Wisconson in a three-point squeaker (missing a 3-pointer at the buzzer). Their first win by less than 10 points was a squeaker over #20 Tennessee (17th game of the season, and after their last loss). Since then, they've had only two games where they won by less than three goals, and since then have beaten both of those teams again by larger margins. So...huh?
After the Florida game, it is obvious they are vulnerable, but they've not had many close games.
