John Collins was a one man wrecking crew in the ACC this year. It’s correct to conclude he’ll need an outside shot in the NBA but it’s hard to determine if he has one or not considering he literally did not shoot 3s in college. Basketball Reference lists 1 attempt in his two year career. ONE. Maybe he can’t shoot at all or maybe he’s a little bit like Kawhi Leonard, who wasn’t known for shooting in college but then showed up to the combine and drained them. FWIW, I read Collins shot well at the workouts.
TLDR version is he can be a real steal in the teens. Lots of star potential that people may not realize.
