It might be wise to have 5 or 6 alternates in place, in case a team cancels. Don't recall the bowl game, but I know that Rutners (Old joke) is filling in for somebody who canceled.
On kind a side note, I'm probably in the minority when it comes to bowl games. I hear constantly that there are too many. I say pooie. Who cares if there are a ton of meaningless games? Nobody's forcing you to watch. There are only 3 games that matter, and those are the playoff games. The rest are exhibitions, but it's still college football. I'll watch part of a meaningless bowl game over a lot of other stuff. Hell, I watch MACtion on Tuesday, Wednesday and Thursday nights....because it's foosballz.
