The Trail gets its name because it "trails" the teams down the court during transition. The responsibilities can be divided into 3 different events (other than special times covered on their own pages, like the Jump Ball and Free Throws).

• Transition
  • This job is simple to explain. Position yourself just behind the last player coming down the court. Stay near your sideline unless you need to move closer to a tightly defended ball.
  • On a full press, officiate the 5 or so players closest to you.
  • When you reach the front court, the transition is over - go to Normal Play.
• Normal Play
  • Keep your top shoulder above the players, but otherwise be as far down the court as possible.
  • Your coverage area when the ball is in your area is above the key (paint) and below the Free Throw Line extended on your side.
  • If the ball goes below the Free Throw Line extended on your partner's side, you must also cover the key (paint). While doing this, drop down below the 3-point arc and stay close to the side line. (If the ball comes back up, move back up where you were.)
  • Do NOT watch the ball. Watch hands and knees of the defensive players in your coverage area. Be especially aware of bad screens.
• On a Shot
  • If the shooter was in your area, watch the shooter until they regain their balance and are "safe". Do NOT watch the shot.
  • If the shot is from beyond the 3-point arc, raise 1 arm at 45 degrees showing 3 fingers until the shot is good or misses.
  • While the ball is in the air, move near the sideline and down to the Free Throw Line extended. (If you run real slow, move only down to the top of the 3-point arc.)
  • Be aware if the ball hits the goal supports, passes over the backboard, etc.
  • Watch the rebounders. Your primary point of coverage is the Block on your side of the key.
  • If the shot was a 3-point try and is good, raise both arms straight up for a couple of seconds to ensure the table sees you.
