Do you have enough motors to make any attachments? One thing I could think of is to make a simple collector/dumper attachment. you could play defense on your opponent by collecting the balls on their side of the court and dump them over the barrier onto your alliance's side of the court. This would not only satisfy the defense aspect you're looking for, but also make you a viable partner for teams that can score, but have issues with traversing the field.

Besides that, You should focus most of your efforts on balancing. If you are a consistent balancing robot, I'm confident that you will be picked for eliminations at whatever regional you attend. Make sure you have your drive base working if you don't have it all set up, because you'll need to practice quite a bit!
