Officiating at the End of Game

Well shouldn’t there have been a 10 second run off 😂
Hmmm...it would sure seem that way. Does the opposing team have the option of declining the 10-second runoff? If not, that raises another possibility....
15 seconds remaining with a stopped clock, no timeouts left, 3rd and whatever in the redzone. Spike the ball, take the 10 yard penalty, and run the clock down to 5 seconds. Kick the FG and win.
