There are many fast pace tactis. Look inside increases pace as well and let you play with your PF and C players while Run and Gum seems to be tactic only good when you have small players with a good offensive skills.
What about full court press? Is it good to use it against a better team or a worse team i.e. when you do not want to risk loose of the game?
I am noob in this game. I've tried 2-3 and 3-2 so far and 2-3 is much better even if opponent scores a lot from distance. You gain more rebounds.
Cheers.
