The deep cross-body throw is one of the most difficult feats a quarterback can attempt — it is not a high-percentage play. You’re throwing against your own momentum, usually with one or more angry defenders in your face, and you’re trying to hit a target 30 or more yards downfield, when you factor in the horizontal yardage involved. And if you’re making a throw like that in a game-defining situation.., well, you’d better be pretty sure of yourself.
