I’ve wondered that myself, Wayne. But it seems to me that the rate of fouls is related to the defensive pace(Sorry if this is obvious. I've only recently started playing out my games.). The higher the pace the more fouls.
Wayne you seem to get a lot of fouls. What do you start defensive pace at?
Something I’ve been playing with is setting the pace based on the refs. I’ll start at 5. Then if the fouls are not to heavy I’ll move it up if needed as the half progresses. This also allows me to keep the fouls low so I can pump up the pace at the end.
My current team has pretty deep bench. This means I can put in subs and not lose to much capability. This helps to spread out the fouls across players if the refs are whistle happy, and keeps fresh legs in the game. If the other team plays their starters a lot this can make a difference.
I did have one game recently where the fouls were 8 or 9 on me and one on the opponent in the 1st half. I was annoyed but we had managed to keep it close despite the fouls. So 10 seconds into the 2nd half We got another foul. I gave the ref a piece of my mind, which of course drew a T. They converted both shots to go up by two, but suddenly the fouls started to balance out and went slightly in our favor. It was probably just the random number generator balanced things out, but I like to think my tantrum got the ref’s attention to how one sided they had been.
