Buffalo was pretty good at avoiding stuffs (59th in stuff rate, i.e. run stops at or behind the line) and strong in short - yardage situations (31st in power success rate).
As he maintains, the Buckeyes did have some success running the ball on the Spartans with powerruns behind some double TE formations in short - yardage scenarios, and on a play where they caught the Spartans in a stunt.
