slightly related to this, but something I have always wondered about is when a team that is ahead by a close margin, and the other team just failed on their last chance to do anything (onside kick, 4th down try, etc) and there is like 45 secs left in the game, and then the backup qb comes in to just do the kneel downs. That's almost insulting to the backup, I have always thought.

...and if the backup gives a shit, it fucks with his career stat lines for rushing with the 3 "carries" for -4 yards.
