Bobby's ejections often seemed calculated to me, as opposed to, say, noted hotheads Billy, Earl, or Leo Durocher who, when something didn't go their way, would go half insane with rage and were completely incapable of controlling themselves. I think most of the time Cox wound up being tossed it was because he decided he was going to make it happen before ever leaving the dugout, that the ejection itself was the point. That other Bobby who was his contemporary (V.) otoh, went out to argue because he was convinced the ump(s) would see things his way if only they'd listen to him explain why they were wrong.
