I agree that my interpretation of the rules as they are currently written it is fully legal for one alliance member to push another over a defense (and even on to the batter).

I do fear that this could lead to damage to one or both of the robots. I have two fears. 1. That due to the potential for robots to be at an angle relative to the floor that the bumpers may override and damage items inside the frame perimeter or for the robots to be locked together. 2. I do foresee a potential for the stuck robot to become damaged because of the potential for a robot to be at an angle relative to the defense and side loading on the wheels to cause damage to them.

I mention the "even on to the batter" based on the fact that in Rebound Rumble my team's alliance was beaten by an alliance who pushed their dead alliance member onto the bridge for a successful 3 robot balance.
