What a crock—the tuck rule is nothing but an excuse for the offense to maintain possession of the football.
The rule states that if a quarterback has the intent to throw the ball, then decides not to throw and tries to "tuck" but fumbles, it's an incomplete pass and not a fumble.
What if the quarterback had no intention of "tucking" the ball? At what point does the quarterback's motion go from throwing to "tucking?"
The worst part about the rule is if the quarterback fully "tucks" then fumbles, it's a fumble.
If the quarterback's arm is going forward and is hit, causing a fumble, fine, that can be considered an incomplete pass. If he knows he's about to get creamed and tries to "tuck" but fumbles—that's a fumble.
Can't the defense get any love these days?
Everything about this rule screams fumble, but because of the rule that split-second between a forward throwing motion and a "tuck" has changed the course of NFL history.
The NFL hasn't changed this rule yet and probably never will—pray that this call doesn't go against your team.
