METAIRIE, La. — Linebacker Curtis Lofton left Atlanta just in time to miss out on the Falcons' best start to a season in franchise history. Now a defensive leader for the struggling Saints, Lofton insists he has no regrets, did what was right for him and is eager to experience one of the NFL's more intense and longstanding rivalries from the other side when the Saints (3-5) host unbeaten Atlanta (8-0) on Sunday. "Yeah, I'm excited to play these guys after playing for them," Lofton said this week.
