Shot creation is still crucial to a roster.
The issue now is just that guys that were only borderline max players can’t justify that contract under the 2nd apron era.
In the 2nd apron era, if you want a real contender with longevity, you need a genuine #1a, #1b dynamic with your max guys. Ingram might not even be a real #2 on a contender so he’s going to struggle to get a max contract.
I think on top of the issue of biological rarity most people are mentioning, who players idolize and model their games after isn’t being mentioned enough. A lot of the most iconic and popular players are all known for their on-ball skills so impressionable players will want to copy them.
