On message: a power player, on a good day, has a better chance of defeating anyone than does a counterpuncher and/or retreiver.
See Roddick in the good old days -- which may be back again.
Nadal really doesn't fit into any one category. Kid's game is built on physical effort, but he's also got all the strokes and is becoming more powerful by the day. Perchance he needs to become a tad more agressive on fast surfaces. Certainly his net-play is highly underated; just look at his percentages after every match.
Oh, what's my order come to?
