You should get 3 trainees with at least allstar potentail. Perferably Perrenial allstar potential. that are 18/19 YO. Do this at the beginning of next years season, becuase after the draft, young players are always cheap. make the maximum height for gaurds 6'4, perferably shorter and mimimum height for big men 6'9. also make sure that they have good starting skills. Then train the same players (3 gaurds or 3 big men) for at least the next 3 seasons. after thse seasons, they will all be quality starters in d. 3. and you said that you just swiched to rebounding? dont do that. stay with the same players for a long time.
