Tony Dungy wanted Saturday night's preseason game to be a tuneup for the defending Super Bowl champions. Peyton Manning was thinking more about cleaning up. The Super Bowl MVP threw three first-half touchdowns and was nearly perfect as the Colts routed the Lions 37-10 for Indy's second win in 13 preseason games. "Detroit was pretty active in their blitzes, and when they're doing that, it's going to give you some chances to throw the ball," Manning said. "Our execution in the passing game was pretty good."
