One aspect I dislike about the UFC is all this weight class hopping by champions. Sure a Silva-Pierre fight would be awesome, but common, it's nothing more than an admission from UFC saying, we got no one who can take titles from these guys.
Lame if you ask me, go out and find someone who can instead of this "interweight" fighting. That or make the champion forfeit the belt if he's going to take on a higher up champion with a match to determine the weight champion.
I say give Michael Bisping his due, he looks like he could take on Silva, rather see GSP stay as WW champion and see Bisping the MW champion.
If they can get Florian-Pierre-Bisping-Griffin-Lesnar as their champions at once, the sport will grow immensely.
UFC did the right thing by giving Lesnar a shot, that will allow the sport to grow substantially by bringing in new fans. They gotta make it easier though to keep track of champions and who are the number one contenders.
All this being said, looking forward to the Griffin-Evans fight, can't stand Evans and hope Griffin kicks the snot out of him.
