Insert usual GDC has the final say caveat and whatnot here....

I feel that it is impossible for your robot to be POSSESSING an opposing alliances ball if it contacts the ball on the side of the robot that is perpendicular to your drive base (for tank drives, it gets into more of a grey area if you are running mecs or swerve or something like that). This seems like the most logical ruling for gameplay as you could still block passes and passing lanes with your robot but you wouldn't be actively pushing the balls away from your opponent and locking down the only game piece in play.
