Lightweight- Tyson Griffin VS Hermes Franca
Griffin is a young explosive beast and Hermes is a calm, calculated fighter. I think they match up good.
Welterweight- Nick Diaz VS Josh Koscheck
I like watching Diaz fight and if Josh's hands are as improved as he says they are I wanna see him try and stand with Diaz's stiff jabs and hooks. They both are very active ground fighters whether on top or bottom.
Middleweight- Mike Swick VS Dean Lister
I just think this would be very interesting. Lister's ground game is arguably the best in MMA and Swick's hands are aguably the fastest in MMA. (I said "Arguably" don't jump me for it) Think it would make a great match-up as I don't see Lister succeeding at every takedown so I would expect a lot of both striking and grappling.
Also Martin Kampman VS Kendall Grove (thats a personal pick as I like watching both fighters, like watching kick-boxing and muay thai styles they use)
Light Heavyweight- Michael Bisping VS Forrest Griffin
One word could explain what i think this fight would be, vicious.
