inside stopper

[Cleveland wins]

Has anybody ever trained one of these 60's overall guys into a freestyle superstar? I just accomplished it today. I have a cleveland cavalier fantasy dynasty and it took me 2 years to train darko millicic into an inside stopper. His overall is 74 and is the starting center on my team, he gets at least one block a game and his blocking stats is 77. Now i'm training for most of the year him in offense and see what happens alon with my younger guys who have at least a 60 overall rating. The other 3 that i have that i will train has between 50 and 59 overall. And now as i just looked at the game which i'm doing now darko is no 75.
