I actually believe the backbot will have a lot to do.
Remember, every shot the "offensive" team scores gives the ball to the "Defensive" team whom could just lob the ball into the back court.
Also the Backbot will effectively get a "fast break" at the period change, giving him a clear shot at the goal.
Any robot that can pick balls up from the floor and isa decent shooter wll make an excellent backbot. (pushing would be helpful to in stopping reloading

)
