Intentional Grounding vs Spike
The main difference between Intentional grounding and Spike is the receiver's involvement in the play.
The receiver is only present at the time of grounding. Besides the roles of the receiver, we can find other significant differences in both plays.
1. Purpose of the Play
The first major difference we can find in both plays is the purpose of the play.
During the use of Intentional grounding, there is no realistic chance of pass completion. The play's primary purpose is to avoid a sack or the loss of yardage. The quarterback is looking to get rid of the ball quickly, so the pass is thrown out of bounds or at a spot where there is no receiver.
On the other hand, a spike occurs when the quarterback intentionally throws the ball to the ground to stop the clock during the ending moments of the game. In this situation, the quarterback is looking for time to plan the next move in the game.
Spike is expected when the team is in the red zone and is looking to score a touchdown before the clock runs out.
2. Penalty
The other main difference between the two plays is a penalty, as intentional grounding results in a loss of a down and a 10-yard penalty from the spot of the foul. The penalty is proven expensive for teams as it results in losing down, and the penalized team is forced to give up the yardage.
But when the quarterback goes for the Spike, the team doesn't get any penalties, and the team can continue their drive without losing any yardage.
3. Requirement of Receiver
The receiver is the main difference between these two plays. For intentional grounding to occur, the quarterback must throw the ball toward an eligible receiver which means that the receiver has to be in bounds and must have the ability to make a play.
However, during the play of a spike, the ball is thrown into the ground, so the receiver is not a requirement. The quarterback throws the ball into the ground without worrying about the receiver's position in the play.
4. Movement of the ball
The other key difference we can find at the time of both plays is the ball's movement.
In intentional grounding, the ball can be caught and returned by the opponent for a touchdown after the ball is thrown. The ball is considered live during the whole play.
But for the Spike to occur ball has to b thrown into the ground. The ball cannot be caught by anyone in the field, meaning it is considered dead once it hits the ground, and the opposing team cannot return it for a score.
5. Time of the play
The time of the play is also the main difference between both plays. Intentional grounding can occur at any given moment, but the Spike is mainly used during late-game situations where the team is in a hurry and is looking to score quickly to win a game.
