What do you mean, thats the entire point of the rule... so teams dn't intentionally stop the clock with penalties. If the clock was already stopped then there is no run off.
what if there is an accidental false start, should the game end just because there is less than 10 second left in the game? of course not. so, now the NFL should regulate the intent of taking a penalty? great, make a false start subjective and up to the interpretation of the ref regarding the players intent. so now rules need sub-rules and penalties have to be called differently depending on when they occur in the game. a false start is different with 10 seconds left than the first play of the game? that makes sense.
This is the direct quote from the NFL rulebook: Article 10 A team is not permitted to conserve time inside of one minute of either half by committing any of the following acts: fouls by either team that prevent the snap (i.e., false start, encroachment, etc.), intentional grounding, an illegal forward pass thrown from beyond the line of scrimmage with the intent to conserve time, throwing a backward pass out of bounds with the intent to conserve time, and any other intentional foul that causes the clock to stop. Penalty: Loss of five yards unless a larger distance penalty is applicable. When actions referred to above are committed by the offensive team with the clock running, officials will run 10 seconds off the game clock before permitting the ball to be put in play on the ready for play signal. The clock will start on the ready for play signal. If the offensive team has timeouts remaining, it will have the option of using a timeout in lieu of a 10-second runoff. If the action is by the defense, the play clock will be reset to 40 seconds and the game clock will start on the ready signal. If the defense has time outs remaining, it will have the option of using a time out in lieu of the game clock being started. NOTE: There never can be a 10-second run off against the defensive team. Because the clock was not running on the penalty (it had just been spiked) there was no runoff.
Obviously many people here forget our 1991 MNF game. clock under 10 seconds, 4th down, time for one more shot at the endzone, accidental false start on the Jets, refs run 10 seconds off and the game is over.
I'm not sure, but I know if any part of Cassel's body was behind/on the line of scrimmage, the pass is legal.
