Ensure you're saving your heavy hitter starters for the more difficult game that week. If you're training 2 players, utilize 1 for the "easier" or less difficult matchup, and then the other for the scrimmage. If training 3, use your best trainee on G1, and then another G2, and the 3rd on the scrimmage.
Heavily scout your opposition, maybe he has a weak starter somewhere in the starting 5. You put your trainee to defend that position, so there is as little damage as possible.
Train w/ respect to elasticity; it will help your players grow quicker and get them to be competitive sooner. If trained right, a player can start being a rotational piece by their age 20/21 season in most cases.
Also, since im training and the players are young and inexpensive, it helps to have more depth pieces in tow, perhaps a guard with high OD, or a scorer who can pack a mighty punch off the bench in a 6th man role can help balance out the training effect. Essentially paying for above-average depth to stay afloat in the league.
