Anyone looking for a player in a PPFD league?

I’ve been intrigued by point-per-first down leagues and am hoping to give it a shot. Has anyone had experiences with this scoring format? Or has a league going that could use another player?

Willing to try any PPFD format, I’ve heard 1/2 PPFD works really well too together with 1/2 PPR. Willing to do a paid league or free league, whatever is available.
