I didn't look at all the teams, but the four I did click on all ran zone defenses. Teams running zone, on average, don't foul as often as teams running either man or (especially) press. Thus, you're most likely getting to the line more often than your opponent (because you're being fouled more often than you are fouling) -- that disparity is going to take away shot attempts from the floor for your team that your opponents are getting due to your lack of fouls. On your Felician team, for example, you've taken 130 fewer shots from the floor than your opponents, but you've also taken 200 more free throw attempts, which at the very least accounts for 100 of those 130 shots (and, in reality, more, because certainly at least some of those were missed front ends of 1-and1's).
