during the 2000s prior to Federer/Nadal fiesta (2005) era, they could have had a great career ala Safin or Hewitt. But 2010s era is just beyond them.
IW 2013 is a terrible example: JMDP was unbelievable for 10 days and it was not enough. Bested Murray, then pull out incredible performance against Djokovic, run out of gas in final against Nadal.
Tsonga at Wimbly 2011, tops Federer (tennistically i mean
) then shows heroic resistance against Djokovic but loses it anyway. Even if he had won, Nadal was waiting next.
Gasquet is dreadful in slams but he is making the best of his draws in MS and it almost always ends up with a big 4.
