Does anyone here run the flex as their main offense? I can’t seem to find any threads or posts about the flex so wondering if it’s any good or not. I only see people running Motion (which just gives a vague descriptionn on it in the game), Triangle, and 5 out.

I run the Flex and do pretty well with it. I run 2 sets with a given team, choosing from Motion, Flex, Princeton, and Triangle.

I've found that the flex is a good offense to run if your best scorer is the SF.

I’ve run the flex in the first 9 years of my current dynasty. I’m about 70% flex, 30% motion, like stated above me, flex was most successful when having your best scorer at SF. I’ve noticed my SG and SF usually lead my team in scoring by end of season
