If you're reading this post, surely you already know about , or whatever we're calling it. During the fourth quarter of the ' win over the on Sunday night, attempted a quarterback sneak on fourth down with le s than a yard to go. Prescott did not gain very much ground on the sneak, and when the ball was spotted, it was David Savard Men Jersey basically impo sible to tell if he'd achieved a first down -- even after they David Savard Jersey brought out the chains.So what did referee Gene Steratore do? He used an index card, seeing if he could slide it in between the tip of the ball and the final link of the chain in order to affirm what he'd seen with the measurement. That was SO CLOSE SB Nation NFL (@SBNationNFL) Here is the explanation for using index card from official Gene Steratore: Vic Tafur (@VicTafur) According to Raiders coach Jack Del Rio, though, it never should have happened. Del Rio said the Cowboys made a bad call in going for it on fourth down in the first place. Cowboys made a big error going for it, on 4th down, Del Rio said. It was ballsy but it really didnt work They gave Sergei Bobrovsky Jersey us the win but official pulled the card out Vic Tafur (@VicTafur) It's Riley Nash Jersey obvious why Del Rio believes the call on the field was wrong. He's the coach of the Raiders, and the call went against the Raiders. It's more interesting to wonder why he thinks the Cowboys -- the best fourth-and-short team in the NFL -- should never have gone it. He seems to be taking a results-driven approach to his analysis ("It was ballsy but it really didn't work..."), which is not nece sarily wise. However, facing fourth-and-1 from their own Markus Hannikainen Kids Jersey 39-yard line with 5:41 left in the game, this was likely going to be Dallas' last, best chance to win the game in regulation. And that's exactly what happened. (After a whole bunch of other weird stuff went down, naturally.)
