It depends a lot on the player and how flexible their mindset is. It's not common though, mostly very good/elite players are the ones that can do that.
A lot of factors come into play...the motivation of course, but also the environment I'd say. There might be a reason that Indiana had like 3 or 4 MIPs in a decade. Part of it is that those players put in work, but probably the team also gave them what they needed to improve.
What about a guy like Chauncey Billups? Iirc he was drafted high but didnt really get it together before getting to Detroit a couple of years later. I didnt really follow him his early years so can't say if it was because his game wasnt that good or that the situation wasn't good for him
I'm still not willing to go that far and say that Ben Simmons will never improve on jump shot as we've never actually seen him even try to do so. That's the difference between him and his other peers in the league. We know what they can/can't do as we've seen them try and fail at it.
