The Rich Eisen Show/ YouTubeRich Eisen lost a bet, and had to pay up by dressing in Ohio State gear.Michigan graduate, and current NFL Network host, Rich Eisen lost a bet to IndyCar racer Graham Rahal. Eisen is a big fan of the Wolverines, obviously, given he went to Michigan. Rahal did not attend Ohio State, but according to Eleven Warriors, he grew up in the Columbus area, and worships the Buckeyes.As any self-respecting fan would, the pair made a bet when their respective teams faced off last weekend. Ohio State won the game in double overtime, and thus, Eisen lost the bet. His consequence? Don some Ohio State gear and give the “O-H,” of course.Eisen clearly needs a little help from Ohio State fans as to the mechanics of throwing up to old “O-H.” Perhaps Eisen didn’t know Ohio State won the past four meetings between the two teams, but now he surely knows its five in a row.At least he’s a good sport.
