Earlier this year, January to be more precise, he said himself (Sasso) in several interviews that one of his legs likely had permanent damage and that his mobility was shot in it (as well as his back. He also said he was actually having trouble keeping weight on (getting down to the mid 130s while in the hospital).
For a guy who last wrestled a defensive style at 149lbs, all those things are very bad for someone going 165lbs for the first time. Especially for a guy who wasn't tall for 149lbs.
One could wager that expecting him to be at the same form he was when he last took the mat competitively in Folkstyle makes much less sense than being pensive or cautious with optimisms. Especially up two weight classes.
Not all of us expect him to contend. Ergo we will not be disappointed when (if) he doesn't win it all. We are all actively rooting for him, though, and will celebrate whatever performances we get from him.
