Wow...where to start.
1. MOST guys in the UFC were NEVER in boxing to begin with. Most have BJJ, wrestling, or other martial arts backgrounds. Very few started as boxers, so it's kinda off to say they couldn't make it in boxing. Mayweather's shot at the UFC makes no sense...
2. No Olympian caliber athletes? You mean like...Matt Lindland? Mark Coleman? Kevin Jackson? Among others worldwide. How about all the NCAA champion wrestlers that are in the UFC and other org's? There are PLENTY of top flight athletes in MMA...even if they weren't olympic boxers. Try not to be TOO shocked if MMA if an olympic sport someday...
3. o and Chuck each got about $3M after PPV share for their fight on Dec 30th. "10's of thousands" for the top guys is a bit extreme...
4. You clearly know jack $hit about MMA. And after what you've said here, you can't argue that you do. I'm sure it sucks to watch your sport flame out. What's the next big fight after this weekend?? When was the last big fight? The finale on The Contender?
