Just as Sunday Night Football was wrapping up this week, Washington Commanders’ quarterback Jayden Daniels took a read option and scrambled to the right. It looked like a routine play, until Daniels’ left arm turned awkwardly in a gruesome injury that led the reigning NFL Rookie of the Year to leave the game early with his arm in an emergency air cast.
