All I know is he joins Borg, Wilander, Becker, and Nadal as the 5 guys in the Open era to have won 2 majors from their first 10 appearances (he is 2 from 10, Nadal, Wilander, and Borg were 2 from 9, Becker was 2 from 8). He is certainly a more complete player at his age than any I've seen, but comparing him to anyone prior to the past 20 years in that regard is also ridiculous.
