Excellent consistency from Nadal, he's reached the last 4 finals winning 1. This is way better than Roger Federer or Andy Murray and there is just one man ahead of him at the moment. Being the finalist the last 3 times is nothing to scoff at, in fact, it adds to Nadal's legacy.
history will judge accurately only at the end of their careers.
these are just normal cycles of the sport.
we will only know down the road who fared best. right now fed is sitting on his 16 slams and clay warrior has his 10.
quite obviously both nadal and nole are going to add to their slam totals over the next 4 years.
fed may snag one as well.
nadal only needs a couple of slam finals wins over nole to start repairing the head to head record in slams.
head to head records in smaller events mean nothing to those who are all time greats like fed, nadal, and nole. these guys measure greatness by the slams they win.
