My son worked with them for a year. Smart guys with a customized approach. Unfortunately we did not see the results that we hoped. My 2022 only gained 2 mph on his fastball after a year with Tread. When it came time for renewal we were told that velocity growth is not linear but I couldn’t swing another round. I think part of it was the fact that there was no relationship in between my son and his assigned coach. They just never clicked and it never worked. I would not do it again. I know I’m in the minority here.
