I think the issue people have with Joubert is that he is routinely dismissive and even contemptuous in his comments about his competitors, and it really makes him sound petty.
In just the last few months, he has dissed Plushenko (calling him overweight and saying he has no chance at a successful return to competition), Buttle (while sitting right next to him at the post-Worlds press conference!) and now Lambiel.
It wouldn't hurt Brian to learn some tact and graciousness, IMO.
Huh? in the case of Buttle and Lambiel, Joubert did not criticize them personally... Joubert is certainly entitled to feel that it's not a good thing that someone can be world champ without a quad. And Joubert is not the only person with this opinion. Plushenko also said he disagrees with what happened. SO did Lambiel and while he didn't announce it so did Takeshi apparently. These men are right to feel that they weren't being rewarded enough for the risks that they took.
Heck, even Paul Wylie and Dick Button agree with Joubert on this issue. You could argue that the ISU also agrees that the quad needs to be valued more, why else would they raise it's point value?
Joubert was just speaking at that moment because he felt something needed to be changed. And the fact is even before that Championship, Joubert was complaining that the quad wasn't getting enough points.
As for Lambiel where was Joubert criticizing him personally once again. And I'm not even sure that Joubert was being mean to Plushenko. He was right to say Plushenko wasn't there physically at that point. That's not mean, it's a matter of fact.
In none of these issues did Joubert get personal.
