i think he does show a lot of patience and self-control. if he didn't, he'd melt down in every tourney and shank his next shot after a swear-inducing one.
i just think that sports media has created a double standard for athletes. it causes us to forget that they are human beings that come as a package deal. we can't pick and choose attributes for them to have. brett favre is getting loads and loads of criticism for not being able to stay retired. people are beginning to even question the morality of it (is he holding the minnesota vikings hostage with the possibility that he might play for them?). but the point is that he was as good of a QB as he was because he had that drive. he refused to quit. we praised him and loved him for that, but that same drive now causes him to not be able to retire and he's suddenly a jerk?
tiger is firey and intense and focused and hates performing badly (could you imagine his reaction to getting owned in monopoly?). this is why he's the world's #1 golfer. it's also why he swears when he hooks a drive here and there.
