A goat becomes a gunslinger

So here's the scene:

A much-maligned quarterback has 2:40 to win his team the football game. Down by 4, he quickly gets into trouble on his own side of the 50-yard line, taking a full minute to march only 20 yards. On third and long, with 1:20 to play, he drops back.

The defenders rush him
They break through
Two of them grab his jersey

Somehow, the frightened quarterback manages to wiggle free of their grasp. He takes a couple steps and throws up a prayer.

Off his back foot.
Into double coverage.
40 yards down the field.

Miraculously the receiver makes the grab, by catching the ball between one hand and his helmet.

From that point it is only a matter of time. An attempt at perfection is lost in one unlikely drive by the opposing team and its "Gunslinging" quarterback. Millions rejoice in an outpouring of schadenfreude.

But what is the margin between Gunslinger and Goat?
