If you don't have the ball, be aware of your teammates and either cut to an open spot to present a possible outlet pass for a pressured teammate, or rotate to fill an open space vacated by a cutter to maintain offensive team spacing. While a quite prophetic statement about life in general, it is even more so true in the game of basketball. Basketball is one of the fastest changing and unpredictable games played. However to learn effective execution teams must practice patterns to refine offensive skills. While this improves a skills chance for proper execution it also makes you more predictable.
Predictability leads to pressure.
Do not change the pattern or system. Rather vary the tempo's and speeds with which you execute the pattern. A dribbler must change speeds and rhythms against pressure. A teammate working to create an outlet pass must vary the timing and angles of their cuts. Do the unexpected but do it with control.
