A second grade teacher in Philadelphia is using football to help her students score big in math. Amber Kiley is running touchdowns in the classroom at MaST Community Charter School II with a little help from the Philadelphia Eagles.

The latest illustration of how fast things can change in the NFL comes in the form of All-Pro running back Saquon Barkley. Only two Super Bowls ago, it was unimaginable that Barkley would go from being the face of the New York Giants to playing for the Philadelphia Eagles-- much less leading them to another Super Bowl.

The last time the Eagles played in the Super Bowl, Saquon Barkley was rooting against them. Barkley, a member of the New York Giants at the time, harbored a bit of resentment toward the team that knocked his squad out of the playoffs in the divisional round.
