It's called Calvinball. :-)
Last night on Brett’s news, he played a clip where the quarterback took the ball and ran to the sideline yelling “new ball, we need a new ball” He was waving the ball around as he headed toward the bench.
Both lines stood up and just relaxed.
On reaching the sideline, the quarter back tucked in the ball and sprinted down the fiels d and across the goal line for a touch down
