Right, but as bob jenkins suggested, perhaps give some leeway during an interrupted dribble? I can see team A having a frontcourt baseline throw-in, player A1 being in the lane for two seconds before the ball is passed inbounds, and then remaining for one second after the ball is inbounds. In such a case I could call three seconds, but unless there is an advantage gained, should I? What if player A1 hits three seconds in the lane but is headed out?
