5. Devin Vassell
With only one NBA season under his belt, it's simply too early to put Devin Vassell any higher on this list, but the potential for a rise is certainly there. The 21-year-old forward was shooting 38.5% from beyond the arc until the final month of the 2020-21 season. A nightmare 6-of-33 month of May dropped his season percentage all the way down to 34.7, but it's clear from his previous work Mr. Vassell knows how to shoot the ball.
Diving more into the numbers, Vassell's sweet spot was the 10-to-16-foot range. His 43.1% shooting from there was fifth on the Spurs among rotation players last season and is the highest 2021 output of anyone on this list.
Beyond his efficiency from that area, Vassell's shooting numbers in college also speak for themselves. Shooting 70-for-168 at Florida State from the outside had him at a 41.7% mark through his two years, which was higher than the college percentages of Lonnie Walker, Derrick White, and Joe Wieskamp.
Ultimately, Vassell's poor shooting from 16 feet to the 3-point line (28.9) and relatively low true shooting percentage (52.4) still land him just above Lonnie Walker but behind everyone else on this list.
