HS FB won't be a major issue in Ohio.
The HS FB games generally kick off at 7:pm, have 12 minute quarters (iirc) and no mediot time outs.
The Buckeyes don't go on until 8:30. So if you have the forsight to put the TV on the right channel and hit pause, you should be able to make it home in time to watch the game in its entirety, skip all the commercials, and catch up to real time before the conclusion of the contest.
It will be a bigger deal for Northwestern fans of course, with the hour difference.
