[Enigma's puzzle]

I think you are looking at the predicament you ran into last year, there was good defensive robots, however, when you can add a offensive robot that an play mediocre defense, it gives you so many more strategy options.

And the best Defense will be keeping balls in a place you can score from, which isnt the defensive side if the court.

A FIRST adage:
You can make an Offensive robot play defense more effectively, than you can make a Defensive robot play offense.
