If possible, I would advise you to try and find 2 players with star or allstar potential, and that are 18 or 19. Make sure that you train only guards or bigs. A young manager trying to do both may end up wasting time and money. Also, buying older players isn't advisable, as players 33 and over start losing skills. If you have doubts on something, read the game manual, and if you can't find an answer there, ask in the forums.
