The_Rookie wroteTrail is table side and balls goes out of bounds above the FT line on the sideline opposite the table ...
For IAABO members only: Opposite sideline above free throw line extended is trail's responsibility (it's in the trails primary coverage area) in two person mechanics (this was a controversial change several years ago, some IAABO veterans still struggle with this new mechanic, it's covered in almost every pregame among veterans). So the trail makes the out of bounds call and moves across the court to remain as trail and administer the throwin, and the lead moves across the lane and stays the lead.
As usual, check your local listings.
