Definitely one of the best
As I say, Nadal is definitely one of the best. But what I was talking about was the discussion about being the very best guy ever. I just can't accept that when Federer holds or equals the open era record for each one of 4 out of 5 of the top 5 titles (the slams + the WTF) that Nadal could rate over him (not unless, and this is possible, Nadal exceeds Federer's achievements - but we can only talk about historical achievements - not future possible ones).
No, career achievement is more important. Federer is clearly ahead of Nadal when it comes to things like number of major wins, number of weeks at number 1, number of major quarter finals in a row etc. Where Nadal enters the GOAT discussion is his ability to beat all of his big rivals more often than they beat him, dominate clay so thoroughly, whilst also being able to win all the majors on other surfaces as well. And as you say, he is one of the best fighters and is also excellent at adapting to challenges over time. Even when a vastly improved Djokovic arrived on the scene, Nadal eventually overcame the problem.
