The Spurs won't trade Tony (before the draft, I thought this wasn't the case). This will be the Spurs' best shot to win another title for a long time, assuming Splitter comes this year. An improved Blair, Hill, RJ, and the addition of Anderson should really help this team. Tony is too much of a talent to get rid of to jeopardize a chance at one more title. While I understand the argument of rebuilding, if we have a legitimate shot at another title, I could live with Tony leaving next year.
With the Suns organization starting to crumble, the Jazz's downfall and the Laker's questionable coaching situation, I think the West will be an open field next season.
