OK. Great. Isn't "who shoots 3s better" a completely different argument than whether or not Moe improved last year over the year prior, or whether or not further improvement should be expected from Snell?
Having watched Snell play, he was a bust in Chicago. His improvement with Milwaukee was so great he earned a $40M+ contract. That's a big turnaround. If he continued his trajectory in his last year of his contract, he might not be in the league right now.
I don't expect big improvement from Snell this season, as he's going to be buried behind ROY winner Malcolm Bragdon at PG Middleton at SG, and Antetokounmpo at SF.
But here, in Stotts' offense, I see him as a starter and he'd get plenty of 3pt looks. Enough to spread the floor.
Mo is a career .315 3pt shooter, Snell came into the league with an NBA 3pt shot. I'm giving Mo the benefit of the doubt that his .351 3pt shooting is a reasonable expectation.
As a coach planning to defend the Blazers, I'd love to see Mo take lots of 3pt shots. I wouldn't want to see Snell taking many.
Given last year's play, Snell would be an upgrade at SF, even if the only difference would be his 3pa and 3pt%. I think he's better on defense, and can also play SG, which is a bonus. Sure, Mo can play some PF, but I don't think we need more PF play, and he isn't that good at it (weak rebounder, for example).
