there are only two reasons that stop a player from improving, not willing to work and physical limitations. None applies to siakam, so I expect him to improve every year for the next 3-4 years. Shooting, post game, handling, jump shot - there are a lot of low hanging fruits for pascal to pick each summer. That's not to say that he's bound to be an elite first weapon offensively one day, he may or may not become that (my guess is no), but he'll be a lot better in 3 years, that much I'm sure.
I don't think OG will be that guy either, they'll both probably top out as elite 2nd options, kind of like where tatum is today. One way or another, we'll need to add a 3rd guy, ideally a kawhi-level creator, but even a next tier player, especially at guard, would make us a top 4-5 team in the league. Especially if that guard is a two-way player with elite shooting ability.
I agree with this, especially OG. Get a superstar here, hopefully keeping both and they are great 2nd/3rd options ......or 2a/b players. Lol
