I think he has proven more than enough times that he is an extremely high caliber athlete. I think he had an epic introduction to the highest rung. He was first a DMR hero and split artist who ran these fast splits for his team. Then he translated that to the open to be a bit more official. Has success there and makes an olympic team.
I think the fact that Nuguse missed the Olympics is weighing on him. And it's like he did all the work to get there so therefore he still has a hangover from the idea of just making the team and doing it. Many athletes don't really think beyond the Trials, to a fault.
So, I think he is in need of a mental break. Maybe he has outgrown the NCAA like some people have suggested. But looking at him he just looks jet lagged and tired. He should take a trip somewhere if he can, have some fun and reset.
