IMO what's not to like?
The power, the determination, the aggression, the unbelievable defensive skills, the energy, the intimidating presence and the sheer staying power.
When he first burst onto the scene with his sleeveless vests, knee-length pants, long greasy hair plus bandanna, he reminded me of a wild Apache warrior who had just escaped from some old-time Western! The only thing missing was a feather stuck in his headband! He certainly resembled no other tennis player I had ever known and that was before I had even seen him hit a tennis ball!
He may be paying the price now for all that physical power and exertion but IMO he transformed tennis into one of the most physically demanding of all the sports. Everybody else had to scramble and quickly get fitter and stronger just to try and keep up with him and that includes players like Djokovic and Murray and even, to some extent, Federer.
Nadal is just unique!
