NBA SF's who are listed at 6'6" or shorter.
(Note - injuries can scramble starting lineups, as can roster peculiarities, so this is only SF's who are both shown as SF on the current depth chart, and whose regular position is shown as SF and nothing else. I'm not counting SF - SG combos. Only "pure" SFs. For example, the Fakers depth chart currently shows Danny Green as an SF, but we know him as an SG for years, and he's strictly SG on bballref.com, so, not counted.)
And these are starters. Not looking at the benches.
Hornets, Miles Bridges, 6'6"
Warriors, Glenn Robinson III, 6'6"
Grizzlies, Jae Crowder, 6'6"
Jazz, Royce O'Neal, 6'4"
For "pure" SFs, that's the crop, according to the current depth charts. Best 3? There's only 4, at this time, starting in the NBA.
The current depth charts have some shorter players at SF, under 6'6", but if you check them, they're normally SG's, or in one case, the Bulls, a PG.
