I can tell people don't watch the Hawks play. People are bringing up stats like the Hawks don't go out of their way to move the offense through multiple players so that's it's even harder to plan for them.
Korver is planned for like he's star level threat. People who think he's just a dude who shoots is really understating his effect on the offense. Korver is typically being guarded by the opposing teams best perimeter defender because of his size, stamina, and shooting ability. Not only that but Korver rarely has the ball in his hands, to attack the basket, by the design of their gameplan. Korver is dangerous because he commands Curry-tier attention when he doesn't have the ball and he's so freakishly efficient that a 3 pointer for him is a better shot than a layup for most.
He attacks defenses by commanding an ungodly amount of attention, his constant movement, the fact that if you aren't within arms reach at all times then he's nailed a shot, etc.
No player in the NBA can replicate what Korver is doing right now except Curry. Korver is probably the most dangerous non-superstar offensive weapon in the NBA. That sounds like an all-star rier talent to me
