You should use the scrimmage to try and top up your minutes so as many players on your team as possible get around 65 minutes for the week to help game shape. So if after your 2 league games a player has played 60+ minutes don't play them, if they have played about 45 minutes u could play them as a backup, if they have played about 20 minutes u could play them the whole game.. No need to even play them in their proper position, its all about getting the right amount of minutes the result of the game doesn't matter. Its better if u find a team your either evenly matched with or worse then so u don't have a blowout
