Strengths:
Long lefty combo-forward who can shoot the ball to the arc, make defensive plays because of his long wingspan and play a couple of different positions. He still has a lot of untapped upside as he becomes more versatile on the offensive end and learns to utilize his length more effective. Very good hands for tip-ins on offensive glass, handle has come along and can pound out couple of times after pulling down defensive board to start break, can also make a straight line drive. Should develop into the type of guy who can create mismatches by scoring over smaller defender or going by less mobile ones.
Weaknesses:
Approaches the offensive end primarily as a three-point shooter but stroke isn't quite pure enough to be that one dimensional; shot low percentage in EYBL and has noticeably big twist in his mechanics. While handle has come along he plays noticeably high off the ground, isn't more than a straight line driver and can really struggle with his decision making, especially when defensive rotations force him to improvise.
Bottom Line:
He's undeniably talented and unique, but offensive efficiency is a concern at the next level, especially given how glued he is to the three-point line
