I don't understand why the UFC is so infatuated with these "super fights". Right now GSP, Silva and JBJ have many people thinking they are unbeatable and their current weight class. If they fight one of them has to lose...then what? Seems like it would devalue the championship if the guy is coming off a loss, even if that loss came at a different weight.
The answer is simple...money.
Your correct if they fight one of them has to lose.
You say..then what?
I say...so what?
Jones almost lost to Belfort via armbar, Silva got his a$$ handed to him for 4-1/2 rounds and GSP was in deep waters after the HK from Condit.
The perception that these fighters are unbeatable is simply that...a perception.
The reality is any of them could lose any fight they are in; it's merely a matter of probability.
And if that happens the massive payday from the superfight is gone as is any perception that Silva, GSP or Jones is unbeatable.
