What does it mean to play with poise?
Poised offensive players make their OWN decisions. These players don't fall prey to the defense by making rushed decisions, especially out of frustration.
At the high school level, turnovers play a huge role in the outcome of games. Most turnovers happen when players are rushing and playing out of control. Playing with poise should be a top priority.
