Three-quarters of the NBA Slam Dunk Contest field has been set, and the confirmed are familiar faces: reigning champ Dwight Howard, former champ Nate Robinson and underwhelming 2008 competitor Rudy Gay. For the fourth slot, the league is holding a fan vote between three rookies: Joe Alexander, Russell Westbrook and Rudy Fernandez. There is no way Rudy loses this, between his rabid Portland base and the legions of devoted Spanish fans who will pump the vote. And while Joe was born with moon shoes on and Westbrook could be the best point guard dunker in a decade, I'm not mad at a Rudy candidacy. Howard, I suspect, might be.
