I'm really tired of this topic, but since it persists as the hottest one I'll chip in again. Let's have a thread devoted to just instances of players not conceding a point for which it can reasonably be said they were aware were called wrong. How many players do you think would appear and how often? Should we start a crusade against all of them because we'll be quite busy on many different fronts.
The fact that this particular case is singled out clearly indicates that it is not irrelevant who the participants were as you claim. Otherwise, we would see hot topics like this at least once a week. Bad rulings happen, players do not concede points more often than not, those erred against move on and do not whine pathetically. If you want to avoid cases like that, the best bet is to advocate replay for the umpire to make better rulings, rather than opine that most players will not rule against themselves on their own in the heat of the moment.
Finally, once again, Blake is not the one with the moral high ground for sportsmanship since he failed in that respect all on his own. He has as much right to it as Gonzo from now on. So if I hear him one more time say something along the lines I don't know how he can sleep, he will definitely make my short list of absolutely despised players. For me, that kind of hypocrisy beats mere opportunism, even if hte latter were without mitigating circumstances.
