Defense, It's still here.

[Molten]

If in POSSESSION of a TRACKBALL, the ROBOT may “bump” the IMPEDING ROBOT with the TRACKBALL outside the BUMPER ZONE, providing the contact is made exclusively with the TRACKBALL.

Take note of this part of the G38 rule. I think that this shows that the original strategy of this thread is allowed. Even if it is not amongst bumper to bumper pushes. It should be allowed as long as they just use a trackball to do all of the pushing. It wouldn't be that hard to design a mechanism that would pick up the ball and hold it in front of itself in a sturdy fashion. With this, it could almost make the ball a part of itself. Of course, to do this for the entire match would cause your team mates to only have one trackball to score with so it is really a mute point. I just thought I would throw this idea out there among the masses and see what you can do with it.

Also, to all of you who believe that defense is unimportant. Just imagine a football team with no defense. Really that analogy works for any sport, football just happens to be a good example.

Finally, a humorous thought to part on. Just imagine if you were to fire that trackball as a projectile. They do not have restrictions on this like they did in the Aim High. Hard telling how fast you could get that ball to. I KNOW THIS DOES NOT GO WITH GP. I just thought it a funny picture to see a ball that size being launched at incredible speed and imagine the impact.
