I'm going to channel my inner Monroe here, but I don't see how you can declare a team better than another when they lost to that team.
First of all, I'm not going to argue that Ohio is a better team than Miami because based on the sum total of what we have seen from both teams I don't think we are. But it is based on body of work and not just because the beat us. I mean, beating us is part of their body of work but it is just that part of it.
Based on your logic there is no way to refute that Ohio is better that Bowling Green, Bowling Green is better than Georgia Tech, Georgia Tech is better than Miami of Florida and and Miami (FL) is better and Miami of Ohio. In fact there are dozens of such arguments that show Ohio is irrefutably better under that logic and also dozens for the opposite. So being in the minority doesn't mean that you are wrong certainly but clearly and obviously living in a world where we think about REALITY in a way a 5 year old should be able to DOES. That statement is CLEARLY LOGICALLY INCORRECT and it don't know how an adult human being could utter it.
I know that the way sports is marketed to us is basically to give fans a lobotomy but seriously as statement like that leaves my jaw agape. Luck plays a part in sports much more than most fans want to admit because of the way it is marketed. But this is obviously so. But Miami beat us they won the right to claim that they beat us. We can't claim the opposite. It also gives them the lead in the East, at least for now and probably permanently. But when you win a championship you won just that - the championship. It is a boost to your argument for being the best when you win it but that's all it is.
I mean we live in a world were MLB teams play their division rivals repeatedly over the course of a season. A season weep over a division rival almost never happens. One team wins one night and the other the next. We accept this. We expect this. Nobody is surprised by it. Nobody claims that one win suddenly proves that they are better.
