I think one reason he avoided a training session w/ Hughes on TUF 4 was to avoid giving his techniques and such away. I also think that he felt uncomfortable around Hughes and that was probably the main reason he left the session. Understandibly, these guys have huge fight coming up. It's the biggest fight of GSP's career and if he wins, his life will change forever. Matt has got to be in his head a little bit; how could he not be? The advantage will be w/ Hughes b/c he's been there many more times - winning the title and defending it.
