The ability to pull opposing rim protectors toward the perimeter with 3pt shooting is more impactful for a big man. Bol shot a ridiculous 52% on threes, and while that number may not be reflective of his NBA percentages, it displays a translatable ability.
Bol’s lack of lateral agility will make it difficult to deploy him effectively at any position besides the 5, though teams may test out the idea of playing him as a 4.
Bol’s size and shooting touch will get him on the floor as a rookie. He’s a tactical weapon whose presence can alter the flow of a game, dissuading shots at the rim and putting opposing bigs in difficult defensive situations.
However, the aforementioned physicality will likely limit his minutes to some degree initially. While the 5 makes the most sense as his long term position, it may simply not be viable until he’s had some time with NBA strength and conditioning coaches.
