What are some defensive strategies that teams were using at the week 1 regionals? I'm been watching videos from TBA and that other site, but I can't see any intentional defensive maneuvers happening consistently. Sure, there's a quick impede here and there, or maybe a nudged or knocked off trackball, but I really see nothing like there has been the past 3 years.

I'm attending and driving at FLR in 3 days and if anyone has any insight regarding defense, it would be greatly appreciated.
