Well we could go back to tradition and schedule the Illinois game as the last of the season... Gee, I wonder why we don't do that?
Seriously, why do you give a shit about The Game? Because year in and year out it brings two of the best programs in all of college football together. Year in and year out it decides who goes where for a bowl game, year in and year out it produces the Big 10 champion. even when, like this year, that champion is not on the field. Often a great performance in the game produces a Heisman Trophy. If either team goes on a prolonged drought you can kiss good-by to The Game being carried nationally, pre- game hype about the last tackle and who dot's the eye, half-time stories about Bo and Woody, people painting their faces maize and blue or donning scarlet and gray wigs.
Like it or not, you're only as good as your schedule and your schedule is only as good as your conference. You want your last game of the year to be meaningful. (and think about how much space we give on this site to fretting about SEC teams that don't leave the South, the entire ACC, the Big Least and Snow White and the 11 dwarfs on the West Coast)
And then think about this: the 10 and 1 Buckeyes travel to Ann Arbor to play 1 and 10 Michigan on a sloppy field, with the Buckeye QB unable to throw (hell, even staying on his feet is a challenge) they win 14 to 9. If you think that team gets into the BCS Chapionship game you're crazy.
