i checked your games this week, and i suposse i know your problem.
You played three times with the same lineup, and your starters play very much especially in your scrimmage where 3 guys had 48 minutes. But you only get training for the first 48 minutes on the training position, so the minutes of the scrimmage are "wasted" for training porpose(if i don't miss player rotation to training spots).
Also gameshape is calculated on played minutes, the optimum is around 55-60 each week but on none training spot i think up to 80 a ok(two times starting with a backup), but in scrimmage let then home and play with your backup and scrubs. On training position i would rotate the starter also in the league games.
