Can't even get out the 1st round. He's not going to be a max level player. He get that check cleared but doesn't deliver when it matters.
Plenty of young college bigs have been stifled by the zone teams can play, and the shytty college PGs incapable of getting them the ball. In the NBA, they'll have the shooting around him to keep teams honest and they'll clear out a side of the floor to let him do work.
His defense needs work, but look at the numbers Embiid & Davis posted in college, then look at Aytons, he's further along offensively than they were at the same age. He's still the number 1 pick.
