2-man mech
 

T-in from end line, 2 man press, A1 on table side passes to A2 on opposite side in bc. A2 begins dribble down sideline. Does new trail follow ball and assume responsibility for side line away from table or does new lead take responsibility for far side line during transition? please cite reference.

T has the ball (e.g., dribble violations, fouls), but L has the sideline.
