End of Quarter Mechanics...

[l3will]

I observed this at a high school varsity game last Friday night.
Just thought that it may be instructional for some.

With 15 seconds left in the first quarter, team A makes a first down
by running. Clock stops, chains reset with ball on A's 47. Then the clock is restarted.
Time runs out without a play being run.

Umpire and Referee take charge of the ball and places the ball at A's 48.
Head Linesman and chain crew flip the chain with clip on A's 45. Head linesman
looks at the ball, says nothing to R and U. HL then has the chain crew set up with
the new ball position and has the chain crew reset the clip. First and 10 for
A at the new ball position. Clip moved at least three feet on the chain.

Not crucial to anything in the game....just looked bad.
