Because he does more than any other player to help children and adults from Haiti, Ethiopia and loads of other places. He put together the Hit for Haiti in Australia and offered to play the entire time because some of the others had matches the next day. All the other players look up to him, and even voted him for an award which shows that he's really a nice person. Roddick (who has a great reason to hate him) said he's really nice, humble and not high and mighty at all. He's normally the calmest player. It was a final and Del Po did stretch the rules a bit, Roger was angry and the umpire told him to be quiet. He was mad and he couldn't help it. You'd react the same in such a pressured environment. He apologised and paid a fine, it happens rarely, it was only a big deal because it was him. He's a brilliant role model, it's only expected that frustration gets to him at some point, it happens to all of us.
The jacket debate has been settled, nike gave it to him and when a sponsor gives you something, you wear it. Roddick wasn't at all bothered. And the crying thing has been done to death. Everyone knows that tournament meant a lot to him, it was a low point. You try fighting with everything you have for hours and hours and failing. Rafa was AMAZING, we all know that. It was a sweet moment and he isn't the only one. Murray got upset this year, Roger said in an interview "i thought he was doing okay until he whispered to me ""i think there'll be some tears"" and i said ""you'll be okay"" ". Nadal also cries. It's great to show how much the game means to you, it just makes me admire him more.
EUROPA - I think you'll find sportsmanship is behaving in a way which is admirable and gives the sport a good name. It's being admired by fellow players and using your sport to do good things. I would probably agree with you if other players felt the same way but considering he's well liked by the two players who have the greatest rivalries with him (Nadal and Roddick) i don't think any of these points are valid. And anyway, what's the point in complaining about it, there's nothing you can do to change it. Whining won't take it away from him.
