Condit:
Insane great fight / finish ratio - 95% the time you know you're getting a war, win or lose, off his back on the feet - he even made getting largely dominated by GSP look good. Its rare for a fighter to do so well and look so good when he is taken out of his game and losing. Never has excuses and usually insightful.
Cain Valesquez:
Outside of the fact, most his fights are championship level in the heaviest division, he always brings the beast, with savage beatings and KOs. Great dude as well - calm, quiet, lethal.
Anderson Silva:
Would have been first last year, but I believe we have seen the best from him, I would actually prefer he didn't come back, he has given us so many incredible moments over the years, wether its joking against the cage as Bonnar tee's off, finishing Belfort with an insane pin point front kick to the face or spending 4.5 rounds underneath Sonnen without a scratch then pulling out a triangle. Funniest man in MMA too.
Mark Hunt:
Kiwi - check, straight shooting - check, always brings it - check. Hunt is the man, full stop.
There are a lot of guys in similar positions for 5th, no clear favourite there.
Gustaffsson, Pettis, Shogun, Machida, Belfort, Cormier, JDS actually, maybe JDS in 5th.
