What's the next move for Nash?

We've heard all the speculation for the past year about Deron Williams and Dwight Howard.

As for Steve Nash? It's been quieter. Daily speculation about his next destination hasn't been nearly as persistent.

Yet entering the opening of free agency Sunday, Nash might be the one A-list free agent who is most in play. He's 38, yes, but he's still playing at an All-Star level. While Howard's fate is likely to be determined by trade in the short term and while Williams apparently has narrowed down his field to two teams (Brooklyn and Dallas), Nash still has a wide array of choices before him, none of which clearly trumps the others.
