Yes. I think it is the weight, and the more he makes it the tougher he gets. He makes it 2-3 days in a row and it takes a lot out of him.
My Wolfpack has also been underperforming as a team at the NCAA tournament. I don't think it is the overseeding stuff with saw with Mizzou in the MAC. There might be some of that but NC state has been placing below guys they have beaten during the regular season, so there might be peaking issues... perhaps weight related.
