This is your reason to drop the axe before it happens.
Picture MR taking the field on 1st &10 at the 50, 50yds to go. He runs a play for 10yds, then after the play spikes the ball for a 15yd penalty. It's still 1st &10 but now we're at the 45, 55 yds to go. Then he does it again. We're 60 yds out. Then again... now we're 65 yds away. He chuckles and says "Well it's still 1st down, we've converted 3 first downs and we've got 30yds of offense.", and Eichorst steps up and yells "All Aboard the Energy Bus!"
If we allow these to go thru we move the goal post back with every raise and extension. If you trip and fall in the mud you may be embarrassed. The idea that if you immediately stand up everyone will know you tripped will embarrass you further so it's best to just sit there till the mud dries up, baffles me.
