If Stan wins, I'd be delighted, too. It seems almost odd sometimes, but among the ultra elite of the golden generation in men's tennis there really are no villains.
Not that he's a villain necessarily, but Murray was a guy who was pretty hard to cheer for especially in his early years. I've softened on him over the past few years but the constant grumpiness gets a little grating after a while.
In a way, the sport needs a bit of a villain or a should I say a more outspoken top player (like Roddick for example). As high quality as the tennis has been in this generation, there really isn't that alpha male personality out there or a rivalry where the players detest each other (McEnroe/Connors for example). Kyrgios competing for Grand Slam Titles would qualify but since he seems to hate the sport, don't see that ever happening.
Nevertheless, this is the Golden Era as far as quality tennis players are concerned and it doesn't appear to be coming to an end anytime soon despite Father Time's best efforts.
