Coach JM, I feel the way you presented your concerns to the assignor was very unprofessional. Dissing his umpire and calling him names is not likely to get you on anyone's good side.
I have worked with many frustrating partners, but I find it easier to just laugh about it rather than feeling all embarrassed. Now if a partner overrules me I am going to have a problem, regardless of how strong an umpire they are.
