I agree about the pick and roll. As basic as it gets, but it is used on every level. You can create mismatches, you can pick and pop, or you can beat the guy on the roll and get an easy layup.
If the team does not know what they are doing stress keep moving without the ball. Back door pass's reward hustle. Go out of bounds and come back in if you have to. Spread out. Run the floor. D up. Play the dribble. If your team is in shape at least you can win just by tiring out the other team.
