In regard to Cuban's comments, I was referring more to the question of whether college or the D-league is a better option for developing players.
It seems to me the D-League would be the no-brainer. You eat, drink, and sleep hoops with no distractions. Yeah the talent pool isn't strong right now, but that's a product of them being NBA rejects. That could change quickly if teams could draft HS players, give them nice contracts, and shelve them in the D-league for 1 or 2 seasons. Do like baseball's farm system.
