dont stick to one plan if you have players who are versatile enough to fill different positions. If even one of you can play as an insert player and do a little of everything you can change things from game to game and wreck people. If they know what youre gonna do every round, they might be able to pick a guy off the break and in 3 man thats a huge disadvantage so early in the game.
