streaky shooter - yes
poor defender - well, not lavine/derozan poor, not monk poor, or god forbid, buddy hield poor... he's in range of bogdan/bjelica defending, below average. he does understand defensive rotations very well, his problem is lack of lateral quickness.
his number one quality is his head, and head is very underrated category in NBA. he's not lazy, not low IQ player and completely opposite of a hothead kid in any capacity. he will work on his shortcomings, so don't expect harry giles offseasons.
if we can get him cheap, i'm all in. worst case scenario - our best 6th player.
but it comes at risk - he's injury prone.
