I’ve used 1-3-1 against good r&g teams and killed them on the other end, with forwards who have good od/id and can score inside.
but generally 2-3 is where it’s at. i’ve KOed a lot of bigger, more expensive teams with my high OD and team SB forcing turnovers, and high hnd/drv on the other end getting their bigs into foul trouble.
ultimately in this game you need balanced players and strategic flexibility. then if you need a mono big later for an extra punch, they’re always on the TL for cheap.
