^ I wonder that, too, or if it'll be several guys splitting them up over a period of time before the next "legend" comes along. I looked up the list of
Slam winners and 'randomly' selected between 2000-2004. I counted 11 different winners in 20 events.
We might be going into a period like that again, as the Big Four fade, unless a new rockstar (or 3) emerges.
Surely, (most of) the Big 4 have a few more Slam titles in them. And if Del Potro can come back in some kind of shape, he might get a couple more. Which makes sense why Dimitrov may have waited too long to make his move, or why timing was against him. I agree that Raonic will only do so much. But when the top guys stop featuring, it'll be interesting to see who rises up.
Moxie, I've posited much the same thing - that once the Big Four start to significantly decline, we'll undergo a (short?) era similar to the late 90s to early 00s between Sampras' peak and Federer's ascension in 2004. Now of course while Pete started declining around 1998 or so, Andre Agassi pulled up the slack a bit and had his best year in '99 and was #1 as late as 2003. But that might partially be because it was a weak era, with a generational gap. Consider that no 4+ Slam winner was born in the years between 1971 (when Pete Sampras was born) to 1981 (when Roger Federer was born). That is the largest gap among Open Era players. The closest was Gustavo Kuerten (1976), who won 3 Slams.
Right now the youngest 4+ Slam winner is, of course, Novak Djokovic, born in 1987. Usually the gap is five years or less. If you start with Ken Rosewall (1934) and you go all the way to Djokovic (1987), the gaps in birth years range widely, with Sampras-Federer being the longest (10 years), then Newcombe-Connors/Vilas (8 years), then Laver-Newcombe (6 years). All the other gaps are five years or less; here's the complete list from Rosewall to Djokovic:
Rosewall-Emerson (2 years)
Emerson-Laver (2 years)
Laver-Newcombe (6 years)
Newcombe-Connors/Vilas (8 years)
Connors/Vilas-Borg (4 years)
Borg-McEnroe (3 years)
McEnroe-Lendl (1 year)
Lendl-Wilander (4 years)
Wilander-Edberg (2 years)
Edberg-Becker (1 year)
Becker-Agassi/Courier (3 years)
Agassi/Courier-Sampras (1 year)
Sampras-Federer (10 years)
Federer-Nadal (5 years)
Nadal-Djokovic (1 year)
Among players born after Novak that have a chance of being a 4+ Slam winner, there aren't many serious contenders within five years. Del Potro is 1 year (1988), Raonic is 3 years (1990), Dimitrov 4 years (1991), and then you have Thiem and Vesely at 6 years (1993), Kyrgios at 8 years (1995), Coric and Garin at 9 years (1996), Zverev at 10 years (1997) and Tiafoe at 11 years (1998). One would think that, among those listed, we'll (hopefully!) have at least one 4+ Slam winner. Of course it could be someone whose name we don't even know yet - but those seem the most likely candidates.
