I usually start the same 5 players for the first two (league) games, then make up minutes for their subs during the scrimmage. But now I'm trying to focus a lot on single position training. I try to get 48 minutes in a single position, then let them sub in another position to get close to 60 for their game shape.
I was only complaining because my tactics weren't followed when there was no foul trouble and it wasn't a (major) blowout. Even a blowout should still give them 48 because of my tactics, but alas, this is not reality.
