Regardless, I have a hard time believing that swapping Duran/Anthony in the batting order makes a team go from worst from first. Nor do I believe that playing a SS who is better suited for 2b would have this giant effect. Really, I dont think a manager needs to be perfect. I think most of the time, the roster is what it is and that GM/CBO is a much much much more important job.
If this team goes on a run now, I dont think its because new manager is better. I think if anything, maybe the change kicked some in the rear. Or maybe its just guys evening out as the sample gets larger. Some WBC hangovers wearing off.
Of course, if the team finishes with a better winning % without Cora than they did with him, Bres will take a victory lap. Cuz hes an azz.
