In American football, a handoff is the act of handing the ball directly from one player to another, i. e. without it leaving the first player's hands.
[1] Most rushing plays on offense begin with a handoff from the quarterback to another running back.
The biggest risk with any hand-off is the chance of fumble on the exchange.
Sometimes called a "switch" in touch football.
Alternately spelled without the hyphen; i.e., "handoff".
