Apparently he's used the same phrase to describe Colangelo's "attack" on him before, so it's doubtful it's a language thing. And if Bargnani is so upset, maybe he can explain what it was that Colangelo said that was unwarranted.
As for the picture, if it was just that I wouldn't think twice, but that, coupled with all the other things, including his apparent lack of desire on the court, makes me really wonder about his dedication. He's shown no improvement on defense and actually regressed in the rebounding department, which was poor to begin with. If he's not dedicated, then why on earth would you want to keep him? You can't change a guy's personality.
