Are the Shaqtus' barbs getting under Dwight Howard's skin? The Lakers' newest center fired back at Shaquille O'Neal on Thursday after O'Neal claimed Andrew Bynum and Brook Lopez are the NBA's best true big men. Howard said he doesn't care what Shaq thinks. But then again, Howard also questioned why the center-turned-TNT-analyst is "talking trash" about his game. While guessing at Shaq's motivation is a fascinating parlor game, there's another question to consider: Should Howard reply to Shaq's criticism? Or should he ignore it?
