Only roster change I would recommend would be to remove one WR slot and one bench spot. If we want we could add a WR/RB slot, making 2WR, 2RB, and a slot for RB or WR (a little more flex with a smaller roster).
My thinking is with 12 teams, 3WR slots (plus most teams with one or two on bench) means probably 4-5WR on each team, 50-55 total for the league, if not more. Removing a WR slot and a bench spot would make the waivers a bit more attractive, the 60th best WR in the NFL is garbage.
Recommend removing one BN spot (leaving 5 total) for the same reason, to make the waivers a bit better (so if you need a player for injury or bye you aren't picking from junk.
Ill give this a few days to simmer then make the change if no objections. Please respond with feedback or ideas.
