20. R.J. Barrett, Duke, 2018-2019

While Williamson drew all the headlines for Duke, RJ Barrett was actually the Blue Devils’ most productive offensive player. Barrett led the Blue Devils in scoring (22.6 ppg, tied with Williamson) while finishing second in both assists (4.3 apg, trailing Tre Jones) and rebounding (7.6 per game, trailing Williamson).

That performance was strong enough to earn Barrett a place as a first-team All-American, joining Williamson to become only the second pair of freshmen teammates to achieve that lofty status. With Williamson drawing a ton of attention down low, Barrett was able to thrive offensively, knocking down 45.4 percent of his shots this season.

The book on Barrett hasn’t been written yet at the next level, but he is projected to be a top-3 pick in June’s NBA Draft. Barrett has drawn comparisons to the likes of DeMar DeRozan and Michael Redd, which could make him an absolutely huge offensive player for whichever team is fortunate enough to land Barrett in the draft.

The one mark against Barrett’s game is his perimeter shooting. Barrett knocked down only 30.8% of his three-point shots at Duke, and he will need to improve his perimeter game if he hopes to become a true franchise-caliber player at the pro level.
