Nadal winning the GS is a slap in the face to every true fan of the sport, seeing it dominated by a player who plays every point camped in the backhand corner waiting for his opponent to make an error.
Can you imagine anyone wanting to pick up tennis after being told that this guy was the pinnacle of the sport? Constant grunting, retrieving, moonballing.
Think of the picture it paints to have him winning all four slams. He'd scare off more potential players than Hewitt and Roddick ever did at number 1.
I'd like to see a player win all four slams some day. But that kind of responsibility belongs to a player like Federer or Nalbandian.
Players like Nadal bring something positive into the sport that wasn't always there before, and that's the physical aspect of the game. Boris Becker did it in his time, and now Nadal's doing it in this decade.
You have to look beyond the days when tennis players wore tight white shorts and had average physiques. At the moment if you go to a tennis court the average player will either be a rich retired man/woman or a skinny kid.
But the trend is slowly changing. The game is getting much more physical, as are the people playing it.
Retrieving the ball is something that requires good physical condition. You just have to look at guys like Gael Monfils, today, or Michael Chang, in the 90's.
Surely you don't prefer the future tennis stars to walk around the court and just stare desperately everytime the opponent hits the ball on the other side of the court.
Tennis is a sport, seeing the greatest fighter ever achieving such success will urge everybody to get a racquet and start playing...
