What you saw with Yazdi is the typical substitution pattern for our nickel defense. We will send 12 men out on the field on defense after a change of possession. If the opponent comes out with 2 wide receivers, we stay in the base defense and the 5th defensive back comes off the field. If the opponent comes out with 3 wide receivers, we go to the nickel defense and the nose tackle comes off the field.

The jumping around probably had something to do with how cold it was . . .

Or maybe Yazdi is just irrepressible?

Thanks for the info.
My memory is fading too fast to remember just what part of the game I started noticing Yazdi doing this. It seemed to me to be rather early - early enough that it stood out to me as strange it was Yazdi hopping on and off the field. 
From your comments I would guess that would typically be David Parry going through this routine - perhaps minus the jumping around?
