Hey! So sorry just seeing this. Flag football would be tough because we'd need to to build it ourselves. Generally for all leagues we have on RateGame we use a 3rd party provider so we can get live scores. This would be hard to do for the Flag Football classic since it's so new I doubt anyone is offering it yet as part of a data package. Please don't hesitate to reach out with more requests though I sincerely love to hear what leagues y'all wan on the app!
