This game was really weird. His SG had a really bad day - 7-21 shooting with Motion against 2-3 is really bad. Did you play CT or did he play TIE? As far as I know, TIE makes your offense a bit worse than normal, while defense remains the same. His PG had a field day like Motion against 2-3 should, so I suspect he had really bad offensive flow. His team made only 21 assists; with Motion against 2-3, they should make at least 30+ assists. He would probably win with RnG. Against a bad outside offense, IMO Motion should look something like this:
(33307237). I know I played against FCP, but if you compare your opponents' Outside shooting (Sensational - 12) and your Outside defense (Respectable - 7), it's a 5 point gap that's the same with my game (my Outside shooting - 8, his Outside offense - 3).
So I guess you won because of his bad offensive flow and his SG's bad shooting day.
