I get the feeling some people are going a bit too far on the offense rather than defense idea. The game designers certainly wanted defense as a part of the game. They provided examples: the legality of keeping bots away from a specific goal (as is shown in the animation.) An example of great game play was an instance I saw of all 3 robots crowding their corner goal near the end of a match to prevent it from being taken and creating a row for the other team.
What they are avoiding is aggressive defense - uses of force rather than finesse. The designers intended for a defense filled with finesse: moving inbetween the bot and the goal; putting your arm in the way of the tetra so it will not fall on, and the like. Examples of bad, aggressive defense are pushing an opposing bot across the field or pinning it to the wall, or pushing them against a tetra until they fall.

Getting in the way of the other robot is how defense is meant to be played, not getting them out of the way.

I get the feeling I'll be repeating that a bit over the next few days
