I think defense is being underrated due to that fact that this scoring object is not big. 1 bot can block 3 legs just by going back and forth a couple feet, 2 could be blocked by never even moving. And if they choose to do this on the opponents side, they will be forced to come around and score on the opposite side of the field, which is being occupied by opposing scorers - and much harder to see what you're doing. The dynamics of this scoring object should be experimented with using live bot defense. Which is what we did. its possible to overreach a defender on the lower 2 levels but the high reachers will need to get in close to score, and may be able to push thier way in. But defense can also be played in keeping the oposing team from picking up the ringers in the first place.
In 2005 we had a higly offensive bot, but we were shut down pretty easily by good defense. The difference there was that the field was spread out, we could go many directions and still score. This rack is right at the center of the field where "everyone" will be. Its going to be crowded and a defender need only play a zone defense and you're going to have your hands full trying to score on it. I know people are thinking of coordinated attacks, but in reality these take time and only work out half the time.
