It may have been a blitz but I'm pretty sure the player who hit Dak was #97 the DE. He worked around the horn and the tackle continued to give ground and eventually lost the guy completely so he nailed Dak. .25 seconds later that thing might have turned into a strip sack. Watching the play again I now see that they only brought one extra man on the pass rush. So that's 5 on 5 with the RB free to pick up leakage. Pollard mis-read it though and ended up stepping to the middle and blocking nobody. Had he slid out to chip to help the ROOKIE LT Dak would have had another second and a half.
