Korver is a weird comp because his peak has been so late in his career. He made himself into a quality all-around player and made his 1st and only All-Star team at age 34 by basically shooting 55% from 3PT for much of the year on the best regular season team in his conference. For most of this younger years, though, he was a guy who made about 2 shots a night inside the 3PT line, was a total zero on the defensive end, gave you 2-3 rebounds and 1 assist, and pretty much nothing else. He was the very definition of 3PT specialist.
Hield is no Jaylen Brown athletically, but also:
* He's more athletic than Jamal Murray, including at the same age
* Was considered a defensive role player earlier in his college career, at least suggesting he can hang at that end
* Scored less than half of his points from 3PT
All the Ben Gordon, Kyle Korver etc comps are either lazily biased or cleverly picked to highlight some equivalency that doesn't really hold up. Gordon was really good for a couple years! Korver made an All-Star team once! Doesn't matter- he absolutely doesn't project as Kyle Korver just because there's some risk of one-dimensionality.
