I've bought 2 PPVs so far, both Strikeforce events, to support competition. I've yet to buy any UFC PPVs, I usually watch them at sports bars or stream them. However, I believe we should support the fighters and pay for the PPVs.
I thought SF:Houston was a good show, particularly the LHW title fight. The other fights were entertaining if not meaningful. Seeing the hype behind Lashley derailed was cool too. That should help staunch the flow of pro wrestlers into MMA.
Gus Johnson is the worst announcer in MMA and the SF team are the worst in sports. They actually make me miss Rogan and Goldberg's idiotic commentary. I especially like how Johnson referred to KJ Noons as the "best puncher in MMA", even though Noons has pro boxing fights on his record.
I think upkicks would give a guy on his back more methods of attack and knees to downed opponents would give wrestlers more pause to just constantly shoot for takedowns. If a stuffed takedown could leave you open to knees to the head, they'd be a lot more hesitant to shoot for the legs.
