If you want to see up and comers check out Griffen/Bisping. If you hate Wandy you'll want to see CC/Silva. If you want drama, Fedor/Aleks is sure to please, along with a little intrique to spice things up. You wanna see Chuck pushed harder than he's ever been pushed, outside of Belfort, go for Silva/Liddell.
Personally I think the sun is setting on a Silva who has provided more exciting fights, both in winning AND losing, than anyone I can think of to date.
Mauricio Rua is who I'd like to see Chuck fight right now, moreso than Silva.
Embrace the pain...train hard bro...TRAIN!
