Yes, but he has the option to take 43 minutes in 1 position for 1 player or 48 minutes in 2 positions for 2 players.
Center:
Starter: P1
Backup: P2
Reserve: P2
Power Forward:
Starter: P2
Backup: P1
Reserve: P1
That should give P1 and P2 48 minutes in those 2 positions. Training something that is already 2 position would be good so you don't lose an oppurtunity to train 1 position. Something like Rebounding or One on One or Jump Shot.
I know it may not be the best solution, but in a walkover it is the best you can do.
