I don’t think the brewers are going to revamping swings. That interview with Brenton Del Chiaro, MILB hitting instructor has the “you be you” approach. Now they will encourage players if they want to make changes, and offer suggestions, but that is the current coaching philosophy.
So likely to see tweaks, and offer data to make suggestions to players to try to help them see what they can do to try to improve, but let them start with whatever got them here and had success in the past.
