The main thing that steps out to me was the fact that he had 15 more rebounds than you and 17 offensive rebounds (that's a lot). As for individual players being better, that doesnt really mean that your team is better overall because of the bench and stamina and game shape and all other sorts of things that contribute to who plays better. By doing strictly follow depth chart it is the coaches job to substitute your starters when your backups will probably be more productive. This could also be a case of poor stamina, but I can't see the stamina for your players but i do not know for sure. Bottom line is that he rebounding you into the ground so although your team is probably a little better overall, with home court advantage he took the edge. I also think he has a bit more depth than your team.
