Was it the "guns" thing or related to Kelce doing his "bow and arrow" thing. He does it all the time and someone did it when they played them and was fined.
I still don't understand why 15 yards isn't tacked on to the 1st down yardage when it happens after the play for offense.
Meaning, why wouldn't it be 1st and 25 instead of 1st and 10 but move them back 15 yards?
