Sorry but I disagree. At the risk of repeating myself, a player doesn't progress because he has put up big stats. He puts up big stats because of his ability!!
To take the example of Millsap. He didn't improve because he put up good numbers. He put up numbers because he was already good when he came into the league (clearly was much better than the scouts gave him credit for). His ceiling was also much higher than the scouts suggested, and he got playing time which would have helped him develop.
If Markel Brown got 30 minutes a night he would probably improve as a player. So progression should be linked to playing time, absolutely 100% (I think it is in 2k15 actually, but I haven't played enough seasons to be certain). But I don't see whether he gets 5ppg or 15ppg makes a difference to his development.
But anyway players can put up stats in 2k15 even if they aren't a good player, same as the NBA. That applies if you sim games or even if you play them. Again it doesn't actually affect their development. If you sim Markel Brown at 30mins per game he might average 15ppg if his tendencies etc allow for it.
I'm all for a dynamic system. I would love to get rid of the visible potentials which are far too fixed, and have a system where some players develop, some don't develop, and it can be influenced by playing time, player character, coaching etc, but even then it should still bel variable... I would love that. But linking development to statistical performance is flawed and its not something I think the community should be putting to the 2k developers- because its an easy option and they just might go for it.
Ps. The upshot of linking development to statistical performance is the best players just get better. Also some players don't put up good numbers but are still valuable and can still develop and regress just like any other player.
