This has been discussed plenty of times before (I believe I started a thread about the same thing a couple years back and others had done it before that). I would love to see it happen, but it never will. With that said, I think realistically the only way they would be able to pull it off is not have a full length NBA season, or maybe run 2 NCAA seasons for every NBA season (maybe combine the 2 classes into 1 for draft purposes). As far as the draft is concerned, have the players stay as they are in NCAA where they max out in ratings etc, but have a secondary layer that is only active once they go to the draft or maybe randomly assign potential based on where the player is projected to get drafted. So for example if the you have the top 3 players in college season randomly assign potentials with a higher chance of good potentials to the top college players (kind of like the RNG for the games).
