From the 2005 Wimbledon to 2007 Australian Open, Federer won 6 out of 7 grand slams. Since then, Federer had another run of 4 out of 7 grand grand slams. Nadal had a run of 4 out of 7 grand slams, with two finals and a quarterfinal. If Djokovic wins this Wimbledon, he will have won 5 out of 7. Do you think any player will ever win 6 out of 7 again?
