Think about it fellas, Jabari Parker's basement is 6th Man of the Year type player as well.
Parker got benched in multiple games for not being able to play defense, against mediocre college teams.
There are going to be plenty of matchups where you can't even put Parker on the floor if you want to.
But a 6th Man of the Year/Situational starter can still be a top 3 player on a team.
Anderson's length, IQ, and skills are beyond NBA ready. There's no risky projections of future skill development or basketball IQ development to worry about. The only "worry" is whether he can gain 10-15 pounds as a 20 year old.
No rational person would worry about a 6'9" 20 year old gaining 10-15 pounds in the future.
