The higher the stamina the better. If you are concerned about minutes, try to win the game by a confortable margin, then you will blow out and your starters will be benched after 30-36 min. It is easier to win with your players performing at full than with them failing in the decisive moment due to low stamina. So thinking "i'll play low stamina dudes because they will play less minutes because of game shape" can give you the opposite result, since they will remain on court for longer minutes - while perfoming worse - trying to win the game.
Plus it is easier for a trainee to get 48 minutes if his stamina is high.
