ABA is cool. Used to be div 1-4. But there's no division 1 anymore because everyoen moved a division down to get a better chance of winning. there's also southbay league. I think the website is sbleague.com. Old NBA rules there, meaning you're not aloud to play zone. ABA you're aloudto play zone defense. Not sure about pacrim though.
Usually the Summer season of ABA is always crackin with gangload of teams on every division.
i have played div 1 when there was one, d2 and d3.
All are competitive.
During the non summer season, d3 is best because there are more teams in each conference.
This season running with some homies on d4.
Should be fun!!!!
Overall ABA is alright -- kinda pricey but good runs
