DeSean Jackson may be a member of the Washington Redskins now, but apparently he still likes the Philadelphia Eagles. That's the only possibly explanation for one of the dumbest punt returns you'll ever see:
Even if Jackson doesn't fumble on this play, he still would have hurt Washington by unnecessarily running backwards. But he did fumble and it set up the Dallas Cowboys for an easy touchdown to take a 16 to 9 lead over Washington late in the game.
In fairness to Jackson, he did redeem himself.
