It's interesting to note how over the last couple of decades that teams that recruit Ohio well make championship runs. The story linked below is a common story each year in recent years when Ohio State plays MSU. They're stacked with Ohio talent.
I've been trying to think of other instances in which a team, loaded with Ohio talent (besides Ohio teams obviously) have made a great run.
I do recall going to a Michigan game in '89 where the program indicated that 11 of the 22 starters were from Ohio (Howard, Bunch, Grbac, etc.)
Were there some other squads from Penn State or maybe Notre Dame that were made great, perhaps at the expense of Ohio State?
