Not really sure what his issues are. He seems to have some good moments and then flounders. Certainly could put on a few pounds of muscle if they are going to use him inside. No matter who is playing inside next year, they need to be more productive than this year's post players.
It's 100% defense for Enuruna. Take the number of times it's obvious to casual fans that he's completely lost and I bet there's 2x more times where the coaching staff is seeing deficiencies.
He kind of reminds me of Terrance Lewis, where they're fine on offense, then you get to the other end of the floor and it looks like they've never played the sport before.
