How do you handle this measurement?

[Reffing Rev.]

Chalk one up for always spotting a first down on a yard line.

If 1st down was on the 27 then the line to gain is the 37, so if our spot is on or behyond the 22 then we've got a first down.

If the 1st down was on the 27.38954 then we may get some confusion.

I don't mandate this practice, but I've learned to see the value of it in between the 20s, so I encourage it.
