He's not getting passed up on athleticism. He's getting passed up on talent. He's not at as talented as Willie (or anyone else on an active pro roster) was or is now. This is crazy talk: "They could sure use a big that can actually play basketball. He'd be more skilled than anyone on their roster almost immediately." Also, if the Kings somehow did draft him, he would be ecstatic.
The Kawhi comparison is absurd. He's not a Kawhi-caliber guy, with or without a face up mid range game.
