And as for Brock with his disease. You said "he changed after the Carwin fight" (@ rabakill). The Carwin fight could have been easily stopped, making it no different from the Cain fight. Lesnar didnt do anything different in either fights. He lay fetal and took a beating. One ref opted to end it, one gave him the chance to go on. Luckily for Lesnar, Carwin half died in the first and he got the submission, but there was virtually no difference between the first rounds.
Which is correct is that Lesnar didn't fight back in both fights, so the referee could have stopped the fight against Carwin. But actually there was a difference: Because of Carwins stupidity, most of his shots landed on Lesnar's forearms. So Lesnar didn't get that hurt. In contrast, Velasquez picked his shots and really hurt Lesnar.
So against Carwin the fetal position was the result of timidity, against Velaasquez it was because of real damage.
Concerning the discussion whether you can learn how to take a punch and how to react on it, according to my observations over the years in the gyms, actually both parties where somewhat right. Yes, you can train to take a punch and to get rid of your timidity, BUT only to some extend. There are people who react better to pressure than other people, and they always will if they have comparable training. I'm not sure whether it's purely genetically or early childhood imprinting, but usually after less than a year of hard sparring you can see whether someone has that "never give up"-spirit under pressure or whether he hasn't. It's the same as in every other aspect of things to train. You can train to run and you will run faster, but only few people can get to Olympic level. And to stay at an elite level of MMA, you have to be one of those guys genetically gifted/correctly imprinted in early childhood at reacting to be under pressure. And Lesnar doesn't seem to be one of those, after his illness even less.
