Jim Harbaugh apparently has brought the ways of the NFL to college football.

Ohio State and Michigan go head-to-head in their rivalry game Saturday in Ann Arbor, Mich., and the Buckeyes apparently had some trouble when they were trying to call it a night Friday. When the players tried to get into their hotel rooms, none of the keys worked.

Of course, it’s possible that this was the result of some faulty technology or human error, but hotel mishaps are pretty common in the NFL, where Harbaugh used to coach. And if it is some foul play, then at least this is far tamer than being woken up┬áin the middle of the night by a fire alarm.
