Bol's only issue is health.
He is an incredibly efficient scorer. He is not as athletic and strong as Giannis, but is a much better shooter than Giannis. Giannis' shooting weakness was really exposed by Raptors in the playoffs.
Think of Bol in terms of a longer Kevin Durant. Of course I don't expect him to have that type of career, but his shooting touch is at that level.
Stop thinking of Bol as a center. That is not who he is.
