If you don't make rebounding a paramount focus within your program, you automatically set yourself up to lose games...and with your actions, by default, you plan to lose games.
Percentage wise, teams that out-rebound their opponents, win games 65.8% of the time.
You are not suppose to sub for the sake of subbing. If a unit is doing great on the floor, keep them in. The game is simple. It doesn't have to be hard.
