Its tragic because throughout the whole fight, Diaz's team were telling him what to do, and Diaz wasn't listening and they were actually contradicting themselves.
They go from the first round saying "cut him off" all the time, to the third round saying "you can't finish him by following him" to "Don't chase him, walk him down." So Nick isn't doing what his corner is telling him.
The frustration alone in what his own corner is saying, tells you that Diaz lost that fight. They're struggling to get a stradegy together to cut Condit off successfully. His corner even helped con Nick into believing he won every round as his own bloody brother told him so!? No wonder he was so pissed off after.
His corner seems to be as collectively stupid as Nick himself, as not once did anyone ever mention going for some takedowns to decisively win a round he so desperately needed.
