I'm tired of the semantics argument about rookies. Mitchell/Tatum should have won, but Simmons got it.
Simmons is the flashier name at this point in their careers. Similar to Lebron, Kyrie, Blake, and Andrew Wiggins, Simmons was the #1 pick and had a good first year of playing. It's a popularity contest.
I'd rather have both Mitchell and Tatum b/c of their shooting ability. I think Mitchell has Wade potential, and Tatum can be like Pierce. I'm not sure what prime time Ben Simmons looks like. I guess its Magic Johnson. I have more confidence that Mitchell/Tatum will reach their potential than Simmons.
