Three biggest things that factored in:
1. Your starting center fouled out, and as a team you gave him 41 free throws. You gave up way too many fouls in that game.
2. As a team, he only had 4 turnovers and produced 23 assists, so he had very impressive passing. You only had 14 assists, and your passing game appears to have suffered with a nearly 1:1 assist/TO ratio. Passing and finding the open man are crucial in this game, IMO.
3. Either he played CT or you played TIE, but he put more into it than you. He probably had heightened enthusiasm, too, seeing as he looked to have been playing TIE for the three games prior to yours on his schedule.
