Re: Players become specialized as they mature?
I would almost say, rather, that their specialty finds them. Venus Williams, in 1999, won Hamburg, and Rome, beating Hingis, Sanchez-Vicario and Pierce along the way. Is she really that different a player? In a way, probably. She's had ten years of practicing certain things, and clearly those things resulted in a player that was designed to win Wimbledon, not Roland Garros.
All players have styles and practice habits, and of course, genetics. What they are at age 18 doesm't always indicate what they'll be at age 26.

Not blind. Not uninformed. We are party to atrocities. But the response of the world after 9/11 is worth noting. Even our most dire enemies offered aid. We should all be so lucky.
