Hockey attacks, especially on the powerplay, circle the puck until you pull the defense out of balance and open a hole to shoot. In hockey especially, where goalies stop 90%+ of all shots on goal, you HAVE to tweak the shot odds in your favor with a clear shot on a goalie who is off balance in the crease or where he is being screened to block his view of the shot. Lacrosse is almost exactly the same.
