I think how teams match up with one another has a lot to do with it as well.
But, that reminds me . . . how comparative scores can lead to ridiculous arguments. If Clemson wins the championship this year, we don't get to play the game since they are undefeated. But, assuming Alabama wins, are they really champs?
Here we go:
Ole Miss beat Alabama
Memphis beat Ole Miss
Navy beat Memphis
Houston beat Navy
UConn beat Houston
Missouri beat UConn
Kentucky beat Missouri (careful - don't want to stop here)
Vanderbilt beat Kentucky
South Carolina beat Vanderbilt
The Citadel beat South Carolina
Ergo, if Alabama wins January 11th, The Citadel will be National Champs meaning no matter what happens, the NC will be found in the State of South Carolina. Coach McDonnell will be damn proud of his alma mater.
