If you go to Nba.com/suns and watch today's Raja Bell press conference video, which Robert Sarver(Owner) Bryan and Jerry Colangelo(GM & consultant) attended, they talk about the JJ situation for the first 10-15 minutes. According to them, the hangup sounds as though it's completely on the Hawks court and that the deal won't be completed until this weekend because of it.
It's a good watch just to hear Suns management side of this JJ fiasco.
