Oh man, I like all these threads on how great Federer will be or Sampras vs Federer and so on... Pretty much within 3 - 4 years, we'll know how great player Federer turn out to be. If he wins over 15 slams including French, all these discussions will be skewed toward Federer. No questions about it. Or if he career path resembles likes of Wilander or McAnroe or most of greats, people will talk about why he couldn't do it.. I bet on Federer turning out to be not so much the greatest in history. Maybe up to 10 slams but include French Open's.. Guys, see you in 3 or 4 years !!
