Well firstly I reject the notion that managers matter very little. Sure, he’s not buying the ingredients but is he not cooking the meal? Lineup construction, pitcher management. Day to day clubhouse management. 2 late season collapses in 3 seasons is a bit of a red flag. Kind of calls into question that the clubhouse is one big happy family.
Again though, none of this is a shining endorsement of the job he did. I need something more concrete.
