"Out of all the crap that happened in the evaluations, the funniest thing to me came when I was partnered up with Richie to do some drills for Matt Hughes. Richie was exhausted, just drilling takedowns and kept trying to "sandbag." When we were asked to do five takedowns, he'd do one, and ask me "that's four, right?" (hoping that the coaches didn't see him). Right away, I knew what kind of heart that guy had. He wasn't there to fight, he was there to be on TV... "
I think these quote shows the first impressions of Mac about Richie, and so I don´t blame him that much for picking on the guy.
At first I couldn´t realize why Mac was allways talking crap about Hightower, and even I still thing he was allways overreacting, this justifies a bit of his attitude.
This shows the tipe of competitor Richie really is and I personally know a lot of people like that, and I can´t say I like them either.
