I have always trained players so I have played strictly follow depth chart forever.
As most of you know it plays like this:
Unless your players have bad stamina, players will play too many minutes unless you get ahead by 20 before or during the 4th quarter.
Your single position trainees will play 48 minutes unless your lead is too big.
Please tell me how to use players in the other substitution modes to get players 60-68 minutes
Assuming you don't need a trainee to play 48
