Here's an average PFPG for all NBA teams:
(http://www.teamrankings.com/nba/stat/personal-fouls-per-g...)I can't say what the standard deviation is, or if a team getting called for 7 fouls in an game happens so often (I think it's possible but would certainly be a rarity indeed, the record low is 5 set by Dallas at San Antonio, November 20, 1999).
This game models itself mostly on the NBA, but the number of fouls should also be based on a few other things besides what is typical. I'd expect lower divisions to have more fouls since defense isn't so good and players are a little more awkward on the offensive end, too. Just watch a few high school and college games and you'll see a "lesser" game with more foul-prone players. But when you also consider how many thousands of teams play in BB, there is just statistically bound to be teams that defy the typical trends. The main thing that requires metastats for analysis is whether or not the overall average number of fouls across all teams fits within the game engine target with a reasonable standard deviation. Rather than odd examples here or there cited as common (and I'm not saying they're not without seeing the big picture). But I know that my team averages 16.8 fouls per game, which is low by NBA standards (18.0 is the record low for a team during a season, done by Houston in 2001-2002), and my opponents are averaging almost 2 PFs less that my team in my team's games, so I see the point that the number of fouls is a bit low.
For the record, one of my all-time favorite players my team ever had is Ramón Mcgregor
(4168577), who used to rack up fouls at a ridiculous rate. I loved him on my team since I would start him in games against my major rivals in the (deparved) hope he could injure some of the other teams' players (he scored at least two big injuries back in the day, as I recall). Sometimes, having these hyper-aggressive players on your team isn't such a bad thing, especially since BB hasn't yet really implemented a serious technical foul program in the game engine yet!
Don't ask what sort of Chunks they are, you probably don't want to know. Blowing Chunks since Season 4!
