well, the obvious things from the box score and PBP are fouls/TOs-- when Peach somehow managed to foul out in the first half (which I've never seen before in 1000s of games-- may want to fiddle with aggressiveness settings) and someone else had 4 in the first half, you played most of the second half with 2nd/3rd stringers, and very tired. Then you turned the ball over a ton (19 times in second half alone).
Not sure how much of it was justified, not going in-depth to analyze teams/individual matchups, but the foul settings are something i'd look at if i were you, especially running press.
