Ohio State survived a tough test from Maryland on Saturday, battling back from a 10-0 deficit before turning things around and pulling away for a 37-17 victory on the strength of a stout defensive effort and some big plays by Marvin Harrison Jr., including the game’s final touchdown. Purdue, meanwhile, is coming off its third loss in its last four contests, this time a 20-14 defeat on the road at Iowa. While the 2-4 Boilermakers aren’t much to write home about, West Lafayette has not been kind to the Buckeyes, as Ohio State has dropped three of the last four meetings at Ross-Ade Stadium.
