Eli Manning's son, Charlie, is dressing as his favorite football player for Halloween. His favorite quarterback, actually. His favorite New York Giants quarterback. It's not Eli. The two-time Super Bowl champion, 44, shared a photo of his son via Instagram on Friday, October 31, showing Charlie, 7, smiling in his blue No. 6 Jaxson Dart jersey, complete with a replica of Dart's famous "good luck" necklace. Dart, 22, is a rookie for the Giants this year and has thrown for 984 yards with eight touchdowns in seven games.
