That doesn't explain the sort of hatred he's getting on MTF, though and this applies to many players who aren't getting as much hatred.
It's disproportional to his tennis results. The higher up, the more haters a player gets on here but Almagro?
I honestly don't know that many players with such appalling attitude on court, in all respects mind you, from sportsmanship to body language. Beats me how anyone can like this guy (despite having quite a game, at least on clay).
As for the second part, I think the chokes like the one against Nadal raise his profile significantly, though personally, for me it's all about his demeanor. I have high tolerance for headcases, but low for dicks.
