“Avengers” fans are begging people on social media not to ruin "Endgame" before they can see it. Some people can't help but ignore the message, including one NFL player. Buffalo Bills running back LeSean McCoy tweeted about the movie's emotional ending moments after seeing the superhero film over the weekend. He questioned a certain character's fate in the 11th hour. Moviegoers were upset. Some even started a petition to have McCoy fired for spoiling the magic.
