If a team that's leading can violate the rules and end a closely contested game by intentionally committing a foul, then if at all possible we need to get that fixed. We extend periods for a whole host of reasons related to fouls.
In this particular case the reason for the exception to the untimed down standard is to prevent A from gaining an advantage - but that's exactly what they get here by intentionally fouling since the loss of down language effectively penalizes team B. This needs to be fixed and there's already been a simple fix recommended. Why not fix it?
I believe the intent of the rule is to prevent Team A from getting a second shot at scoring by throwing an illegal pass.
What would the "fix" be for these two plays?
Team A is down by 6 pts. 4th and 10 from the 50. A10 takes the snap just before time expires in the 4th qtr. A10 runs to his right and has a clear running lane. He gets to the B-10 where he realizes he will not be able to score so he throws a pass to his teammate who catches the ball in the end zone. Would you change anything with a rule change here or keep the rule as currently written?
Team A is down by 5 pts. 4th and Goal from the 10. A10 takes the snap just before time expires in the 4th qtr. A10 runs to his right and has a clear running lane. He gets to the B-5 where he realizes he will not be able to score so he throws a pass to his teammate who catches the ball in the end zone. Considering the proposed "fix" to extend the period, we penalize team A, 5 yards from the spot of the foul and loss of down, extend the period for team B. Team B (now team A) snaps the ball but it is muffed. The defense picks up the loose ball and runs it in for a TD to win the game. Now the outcry is why did we extend the period.
I just think that we will never be able to get the rules to match every possible scenario that only happens once every 100 years so in my opinion it's not really broken. Now if we get 2 or 3 more of these this year then it my be worth looking at.
