The Ohio State Buckeyes are very good this season.
Their only loss occurred against a top ranked San Diego State team. They also beat Cincy 81-53 and #21 Texas Tech. They are big and can battle inside. Offensively, the Buckeyes are more efficient than Duke, averaging 116 points per 100 possessions, ranking them sixth in D1 compared to Duke with 112.

Furthermore, the Buckeyes' defense has also been spectacular and very good at guarding the perimeter which is the strength of Duke shooting 3's.
I like OHIO STATE to keep this game close throughout.
