Rating point totals don't mean much of anything.
Their PG was faster and a way better BH/Pass option than yours. Stronger perimeter threat too.
Their SG was way more athletic and faster with elite defense, so he had whoever he was up against locked up.
I like your SF, though theirs was more athletic and really strong defensively so they were up to the task.
They have amazing rebounding in the post.
Your PF had the edge outside of rebounding; theirs looks good in the post.
Their C might have been the best player on the floor, a human coach would have got him the ball more.
1 to 12 I like your roster more, but that team had some advantages in the starting five. It's not shocking that they won.
