GENIUS Idea To Stop The Clock!

[George Cantstandya]

Probably because it would result in a 5 yard penalty and a 10 second run off.

Quote:Section 7
Actions to Conserve Time
ILLEGAL ACTS
Article 1

A team is not permitted to conserve time inside of one minute of either half by committing any of the
following acts:
(a)   a foul by either team that prevents the snap (i.e., false start, encroachment, etc.)
(b)   intentional grounding;
(c )   an illegal forward pass thrown from beyond the line of scrimmage;
(d)   throwing a backward pass out of bounds;  
(e)   spiking or throwing the ball in the field of play after a down has ended, except after a touchdown; or
(f)    any other intentional foul that causes the clock to stop.

Penalty:  For  Illegally  Conserving  Time:  Loss of five yards unless a larger distance penalty is
applicable.

When actions referred to above are committed by the offensive team while time is in, 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 game 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, in which case the  game  clock  will  start  on  the  snap  after  the  timeout.  The  defense  always  has  the  option  to
decline the 10-second runoff and have the yardage penalty enforced, but if the yardage penalty is declined, the 10-second runoff is also declined.
