Listen, I'm a big Wiggins fan, but the dude still looks awkward dribbling the basketball and clearly doesn't have a deep understanding of basketball yet. He simply needs more experience. The problem with the Wolves is they didn't force feed him the rock enough thus far, and now he's going to have to share touches with guys who are more polished coming into the league which may hinder his development--and he doesn't have the personality to demand touches.
I also think Giannis needs more time to prove that he can be a big time scorer on top of the other stuff he brings to the table. If he ever becomes a good shooter then the league will have a problem.
KAT...he has a ridiculous array of skills on both sides of the floor. I've never seen a rookie come into the league with no real weaknesses. He has post-moves, can finish with both hands, can shoot off the dribble, turnaround jumper, can shoot the three, can set screens and roll to the basket well, makes great cuts, can dribble, great on both the offensive and defensive boards, blocks shots, great defensive positioning and awareness. I feel like once the current crop of stars age out of being great that KAT will be the best in the game.
