MMA is boring these days
Early 2000's was the best days for heavyweight MMA with Pride and early UFC. You rarely see ground game like this anymore from heavyweights. watching Mir break bones was so satisfying 
Prode ruled back in the day. They didn't give a crap if you juiced. Just do whatever it takes to kick ass -- and they were allowed to kick some major ass. Sucks that the Yakuza corrupted everything and started fixing fights.
One Championships seems to be really becoming a force in MMA and seems to have the best chance to break the UFC monopoly. They seem to have the money and they are taking care of the fighters better.
