Could Utah have beaten Florida head to head? We will never know. Could Florida have beaten Texas (who should have been there instead of Oklahoma) in that bowl? We will never know. The BCS is a rediculous joke. Until there is a playoff, calling anyone the national champion is an assumption.
Good questions, but 1) Utah was out of the picture before the season started. Not their fault, but if they want to be in the BCS, they have to change their conference or lobby to have their conference included. That just might happen or at least a waiver or two. 2), As to Texas being in the championship bowl, again, that was setteled before the season as to the tie breakers. Everyone, in their argument about Texas going instead always seem to forget Texas Tech who beat them. Again, the rules for tie breakers in the Big 12 were set before the season started. And the argument that UT beat OU on a neural field is one thing, but if you change tie breaker rules for that one purpose, you are making a change that affects only one game in the Big 12, so the whole controversy could still happen if it included a team other than OU or UT. 3) As to a playoff, until the BCS, this argument seemed to happen every year so they pitted the top two teams in the rankings against each other, more or less using the season as a mini playoffs. Because there are so many colleges that play division one football, the rules for a play off would mean that many conference champions could not be included and what would happen to those conferences such as the Big 12, SEC and Pac10 who have multiple great teams? If you think there was controversy this year, think what it would be like using conference champions, even if every conference had it's own championship game. But if that wasn't the rule, using conference champions, then you would have to use the polls again, and therein lies the biggest problem. Just as we have here today, a team has to be voted as to whether they are the champs and not decided on the field. I could go on forever on this, but I think you get my drift. No matter what you do, there will always be a controversy as to who is #1.
And as for Bradford, I think he should go pro now while his stock is at it's highest. No matter when he comes out, he will be a high pick and therefore will likely go to a pretty bad team.
I wish only the best for this young man. Most people only know of his football prowess, but he is an excelent student, model citizen and athlete. The state of Oklahoma can be very proud of this homestate young man.
Move over Ohio State, Oklahoma is now the Rodney Dangerfield of major college football.
