I hate Frank Mir, or should i say 'hated' frank Mir until i saw that video. Didn't realise he was like that and could talk so much sense.
As for Leeroy, I in no way think he is in the same A-hole league as Junie Browning (yet) and from what we've seen he is an antagonist but has not actually broken any rules as such.
He's like a smaller, louder mouthed, more annoying version of that head kick guy with the afro from the last season. (i can't for the life of me remember his name)
Jamie Yager. Yeah that guy was a douche. I don't particular care for Mir as a fighter, but as a speaker/commentator/analyst he's pretty goddamn awesome.
I won't mind Leeroy's antics so long as he backs it up in the cage, and comes no where near as close to Junie Browning's 'legacy of douche'. Man, when Jamie Yager quit in the ring I couldn't believe it. I think Leeroy's got heart though, personally
