Given the fact that both men were born in August ten years apart (Sampras 1971, Federer 1981) it is relatively easy to compare their achievements at the same age. That's exactly what they did on
For me this is by far the best Federer/Sampras compare because both are always compared at the same stage of their career (actually USO 1997/2007). At first sight it is interesting to find a lot of other similarities like birth date, weight, height, number of titles won, sort of titles won, winning percentages, most of the titles won at Wimbledon and USO, no FO title etc. Comparing the numbers Federer sometimes looks like a Sampras clone ten years after ...
Very interesting also the comparison of their rescaled ranking points at
It gives you a hint when the players peaked. Sampras hit his ranking points peak in 1994 (more than 6500) and he nearly equaled that in 1995. Federer hit his points peak (until now) at the end of 2006 (more than 8000 points).
For me this graphic reflects very well their careers at the same stage. Sampras started earlier to win titles (and ranking points). His uprise was straightforward till 1994, then he ups and downs. Federer started later but peaked higher. That reflects his stronger domination of the game.
But it also gives you an indication of the possible future. Surely Fed will have ups and downs like Sampras had from now on (you can't win always 3 Slam a year), but he should stay on a higher level (ranking points wise) than Sampras and surpass him with his achievements. But of course you never know!
