He’s entirely useless when not hitting threes
Although a bit harsh, you're pretty much correct. He's not a great rebounder, definitely not a great defender, doesn't dish out many assists, so if he's not hitting 3s, at best he's forcing the defense to at least adjust towards him, which might open up some driving lanes for others
I love Pope's system, I'm a big fan of Zoom concepts and I think Pope does a great job teaching his guys the read/react actions that go along with Zoom, which is why his teams usually score really well. However...
I'd love to see more Kobe-sets - have him set a cross-screen to get someone a layup, then come off a down-screen or stagger screen. Zoom is great, but it's a bit predictable and if you're able to switch screens, it can give the Cats problems. I'd love to see a series of sets for Pope to run when Kobe is in. He's great after timeouts, but some sets during the flow of the game as well
