So if you know gameshape is important and you aren't training anybody (by the looks of it), why would you ever book a scrimmage in the first place?
I just glanced at your best player, Gattoni, and he played in 4 scrimmages last year prior to your elimination from the playoffs. In every case he had already played plenty of minutes in the 2 games prior to the scrimmage that week. In one of those scrimmages you played him all 48 minutes. My question is why would you do that in a meaningless exhibition game? You also played him in a cup game that you won by 75 points over a BOT where you clearly didn't need him at all. All any of this did was make his gameshape worse for every game that followed the next week or longer and it gained you nothing.
As for options? Never, ever play somebody in a scrimmage if he's already played 50-75 minutes that week. You're only hurting yourself. If you do book a scrimmage, dress 3 players (the minimum) . Start your bench guys so that they get 50-75 minutes instead of 20-30 for the week improving their gameshape. Pick up some cheap players for your roster or pick up scrubs for $1000 on the transfer wire and then cut them before the Monday update so you don't pay their salary. Lots of options.
But I am curious on why you don't train players? It's free and it's the best part of the game. And it's the reason most of us book scrimmages in the first place.
