Did you happen to catch what Calvin said when they were discussing Mario Elie's new coaching role dureing the SA game? Something about, "getting your due" and "what about my due?" Not to throw things in a different direction, but I think Calvin should look into coaching. I don't think you would see the same high spirited color commentary, rather I think he would be a perfectionist. Whether or not it would work in the current NBA is an altogether different story.
