Mmm, strange, very hard to see the similarities and causes. I see why you include Santoro and Bahrami (I don`t agree at all, but it doesn`t matter), hovewer what on earth Sampras is doing here then and - especially - Becker?
Becker? He won Wimbledon at 17. At 17 you have nothing But talent. Here's a short clip of an interesting TB http://www.youtube.com/watch?v=N3rGPOde5Ss
Sampras - to ask me why i think Sampras is among the most talented players in the world is like asking me the same about Federer. Serve, BH, FH, volleys, decisions - all about talent and work too ofc, but the base is very clear.
I would ask - why wouldn't you agree about Santoro's talent? That's pretty strange to me tbh, Bahrami perhaps you're right (but we both haven't seen much of his tennis, maybe i've seen a bit more, but still not too much), but Santoro is the illustration of what a God gifted talent is.
