None of that should have even been happening. At the end of a game like that it's the responsibility of a running back to WRAP UP THE BALL and get to the deck. Hill was using one arm trying to stiff-arm a Steeler and could not perform that basic task, they DID NOT need a 1st down, all they needed was to run 3 plays and take the chip-shot FG and they win. As a ball-handler you KNOW the other team is desperate to get it back and protecting the ball from being stripped out is job #1.
If you don't need a first down, why even run the ball? Take 3 kneees. Poor coaching first and poor awareness by Hill.
