First, who had a problem with Kimbo? I assume the spotlight you mentioned was his EXC main events. I had no problem with that. They were against journeymen heavyweights and brought in tons of eyeballs to MMA. Whether it was the fights with Tank, Thompson or Tuf10, it was good for MMA.
There's no doubt Brock in MMA is good for the sport. Do you think the shows he was on do as good business wise? Who knows how many people ordered, watched their first MMA show because of Brock. No way to tell how many people became fans after watching UFC 81, UFC 87, UFC 91, UFC 100, UFC 116 or even 121. Hell, I'm sure some fans were created because Cain knocked him out.
I don't see one negative result of Brock becoming an MMA fighter like he did.
As for your issue with people proclaiming him #1. They only did after Fedor lost by tap out. Someone had to be #1. If you're ranking, who's #1? A guy who was a borderline top ten heavyweight who subbed Fedor, or the #2 heavyweight behind Fedor?
The UFC pushed him as the best thing since sliced bread because he appeared to be unstoppable. He beat the only man to beat him. He took a pounding from Carwin, didn't quit and ended up submitting him. Who knew he would come out like James Thompson and freak himself out at the first punch?
I will say my jaw was wide open when I saw Velasquez bounce up from those two takedowns like they were nothing. It was insane. There may not be any man alive who can take him down without knocking him loopy.
