Someone mentioned Mitch’s offseason work with Tread in the post-game thread. I knew offhand he had worked with a third-party in the offseason but I looked Tread up and browsed their website. Brubaker is apparently a Tread client as well.
This testimonial video is on their front page. Both eyebrows raised at the point in the video where Mitch says things were over-complicated for him before Tread, but Tread simplified things for him and “bang, it started clicking.”
