The best way to defend against the triplets is to keep pounding them from the sides and front and eventually their "unbreakable" treads will break immobilizing them the rest of the match. I noticed this a few times at GLR, twice in particular during the finals matches. Also they rely on sweet spots during auto, block the sweet spot they cant score with out readjusting. But other than that very good robots, with great scoring capabilities

But just FYI.
