but if you have le bron james etc. you have to change training dramatically, because now adays a player with one season training is much better then before ;) So the fast training is very unrealistic.
And drafting people who reach their cap, is sully ;)
The other point is you start with 18 year old player, normally they leave college with 22/23(?) so till that point must player finished their progress, so maybe you have then your LeBron.
