I still can't believe they/Dak thought running the ball with 14secs left was a good idea, even in a best case scenario they would've only had 1sec left.
They got greedy seeing the 9ers were playing that soft defense. 14 second was enough to get two shots at the end zone. They wanted something shorter but you gotta pay the clock. That's not the time to get cute.
That Gregory holding penalty fukked them over. They could have gotten the ball back with enough time to not need to rush.
Bottom line is Dallas is a poorly coached and poorly prepared team. They didn't make enough adjustments and continually shot themselves in the foot.
