'The game is all Eagles after that, and at the start of the fourth quarter the Eagles are up 24-7. Jake and Scott are so happy, and I am beginning to imagine the conversation I am going to have with my father when I get home--how proud he will be of my yelling whenever Eli Manning was trying to call a play.' from The Silver Linings Playbook by Matthew Quick What does 'call a play' mean in American football? Please help. Thank you.
