The best thing chuck could do is to work on his defense. He spent so long fighting grapplers that he's forgotten basic striking defense. When he's come up against strikers lately, he's lost. EVen beofre then, when he'd fought other strikers, he'd get tagged a lot. His Trainer, John Hackleman has some odd ideas for stand up fighting. The "guard" chuck uses standing is the one Hackelman teaches (check out crossfit.com for videos of hackelman teaching). It's designed to let you throw hard left hooks whenever your opponent steps in, but leaves your chin completely exposed.
It worked for Chuck when he was fighting BJJers, wrestlers and people a lot shorter than him with pretty sloppy technique (silva), but hasn't looked good against tall fighters (long reach) or people with decent striking ability.
Then again, chuck is getting old for a fighter. He's 38 years old, and not everybody can be a Randy Coutore. He might just be at the end of his career.
