That is something I think often gets overlooked when people talk about them. I know they've been 1-2 since 2005 and have won almost all of the majors in recent years, but are they really from the same generation? They are half a decade apart in age. And 5 years is a LONG time in tennis. Let's just consider the age difference between Pete and his rivals: Pete Sampras's rivals: Andre Agassi: 1.25 years older than Pete Jim Courier, 1 year older than Pete Goran Ivanisevic: one month younger than Pete Boris Becker: 4 years older than Pete Michael Chang: 6 months younger than Pete Patrick Rafter: 1 1/3 years younger than Pete How many players born after 1975 were ever really considered to be Pete's rivals or from his generation? Meanwhile, consider that three much younger players are considered to be Roger's rivals: Rafael Nadal: 5 years younger than Roger Novak Djokovic: 6 years younger than Roger Andy Murray: 6 years younger than Roger Plus you have Del Potro (7 years younger than Roger) and Monfils (5 years younger than Roger). So I think it's very impressive to consider how well Roger is doing considering he at least 5 years older than most of his current rivals.
