I just think enough is already being asked of the best football players at the college level and some level of uncertainty as to which was truly the best team at the end of the season is entirely appropriate, and really just part of the fun, allowing fans to argue, etc., in a good-natured way.
If not knowing who the real champion is because its not decided on the field, why does nobody else do this? No other sport and no other level of football - even college football - does not have a playoff. I never understood the claim that having it undecided was somehow "better".....but only for major college football. Not for anything else.
