I don’t know that there’s a problem that needs to be solved here. 3.0 has made recruiting more competitive. If a team has a roster comprised of only NBA talent, they have likely gotten pretty lucky, winning a lot of RNG rolls. And the better a team is, the more promised starts and minutes hurt, so there is some built-in pain in the risk/reward calculation. I probably agree with mully here, this seems like a solution in search of a problem. I wouldn’t make this any kind of a priority for the developers.
That said, I don’t think there’s anything wrong with making promises impact a player’s work ethic, and in extreme cases causing transfers, past the freshman season, if that’s something the developers feel like tweaking. Especially for players with a playing time preference, it would make sense that their work ethic be more sensitive to demotions and PT decreases. But I would hesitate to support anything that significantly increases transfers. I think most of the effect should be focused on the individual player’s work ethic, and the coach’s reputation, if such a tweak is made.
