I really think that there isn't a wrong answer to this one, all of them would be an upgrade for the roster. Arenas and Roy would be a wild combo back court, Nash would be handing out assist like candy, Davis would be a tough PG.
Nash being older and the team just not there yet kinda makes me lean away from him, Davis isn't my type of point guard, but he is an upgrade, and Arenas has a wild swagger to him that might be good for this team or it could be a horrid problem.
