His defense rated much stronger (like elite) last year and replacement level this year. Will be interesting to dive in and see what changed.
His team's defense splits with him "ON" court the last 2 years against top 200 comp, garbage time filtered out.
Opponents shot better at the rim and got there more often this past year, which is a bit troubling for him. They made a ton more 2pt mid shots. The team forced less turnovers and gave up more rebounds.
Overall worse in almost every way. Could be them going up a level of competition to AAC. Could be laziness after the run last year. Could be the guards played worse and he had to clean up more.
Here's his personal stats the last 2 years. Block rate was slightly higher this year, so doesn't seem like his activity level decreased. He personally fouled less frequently, so that's a great sign (more blocks with less fouls is very good). His rebound numbers did get a little worse, but still elite.
I'm betting the tape would show a lack of focus by the team on defense and especially their guards getting too big for their britches and letting too many guys by them to the rim and not putting enough pressure on the opponent.
