Ferrer's class is some stupid perception that you lot have developed because the guy has no character about his game therefore he must be classy, because he doesn't do anything to get the crowd involved and because his tennis is uninspiring and workmanlike. He aimed a ball at a baby once - yes very classy guy is David Ferrer.
The very fact that you can bring up the "baby" story alone shows your bad faith. He lobbed a ball in the stands. Stupid American media decided he had "aimed a ball at a baby." That was one of the most ridiculous "moutain-out-of-a-molehill" case I've ever seen. End of story.
His only true misstep was the one with the lady umpire, and I tend to think no one is exemplary enough to have NO cases of bad behaviour at all in a long career.
His class is not a "stupid perception". I happen to like people who are modest, soft-spoken, speak well, write well, and act respectfully (although I'm not surprised that you don't value these qualities much).
I love a guy who quotes reading as his favourite hobby, who has brains, and says culture is more important to him than sport.
Some people criticize Ferrer for treating tennis "like a job"... Well, I think he's just aware that there's more to life than tennis and sports, and that's a good thing, for me, not a bad thing.
As for his uninspiring tennis, well, his attitude is certainly inspiring to a lot of people. Having no natural advantages and yet, being able to compensate with perseverance and dedication... That can be very inspiring to many.
