If you knew how the measurement is taken, you would know the measurement was correct. The stick is not part of the 10 yards, and neither is the eye bolt.
The chain is 10 yards. Everything else attached to the chain is just to make the measurement easier.
You see that even Spurrier was looking at where the chain was connected to the eye bolt.
That is correct. If Homer on the chain gang is going to cheat, he will do it when he attaches the clip to the chain at the nearest yard marker.
That’s simply not true. 10 yards goes from outside of stick to outside of stick. If any of the ball is past the stick it’s a 1st down, if none of it is it isn’t. BOTH eye bolt AND BOTH sticks are part of the 10 yards.
