Which seems like an easy thing they could have done years ago. I'm not all that familiar with what tech they're planning to use here, but it'd be pretty easy to put a laser in the first down marker and turn it on when they need to make a "measurement" rather than taking 2-3 minutes for the chain gang tome out and do their thing.
