That is a tad revisionist. He struggled in the PnR and didn't shoot as well as hoped, but it happens for a freshman. If he is our backup big, we are in trouble though. I agree, but I wouldn't say he is awful. He provided some decent minutes at times. Give him more development as a big and he could be serviceable.
Oleg Retsov, was awful. Yaya, is not good. I would not classify Luke as awful. I would say unpolished and needing a lot more work. He has some good tools. He only attempted 30 3's, that is a small sample size for someone who needs more attempts based on practice reports. (Or Moser fooled us all, that is also possible)
