It's not a good idea...it's a great idea!
1. The best fighters at 145 and 135 will now make a lot more money (imagine how many FOTN bonuses they're going to steal?)
2. The UFC has two more champions and divisions to promote so every PPV card can have a title fight and/or #1 contender bout
3. We won't get stuck with main events like Mir-Cro Cop.
