I tend to fall on the side of coaching not really being all that important in pro sports, most of the players are who they are, but if veterans with track records all instantly become turbo asscheeks, and importantly for the Cubs, in the same manner (ie they all are just getting completely crushed for a comical amount of homers, not sucking in different ways), I have to question what the coach is doing. Like Hottovy can’t come up with a tweak that prevents even a single arm on the team from giving up massive power like its the home run derby?
