You are looking at the tape in the wrong light.
You need to look specifically at the skills and athleticism.
Wiggins is 6'8 200 pounds. Dribbles like a guard. Has a nice jumpshot. Athleticism is out of this world. Fast. Can score from anywhere on the court using a vast array of offensive moves.
What guy can you mention had all those attributes in high school? He dominates everyone / every game he plays in. No one is even close to being on his level.
He will play the 3 in the NBA imo.
To your last point, I am also excited to see Shabaz play this year.
Although Id rather has Zeller in the draft. Hard to find true 7fts that are that polished.
