That last play wasn't bad. He had nothing there. The last thing he needed to do was take a sack.
I agree and I think Dak did great to not get sacked, I still don't know how he managed to avoid the sack & stay up and roll to the left, unfortunately he did all that to throw a game ending pick,
Somehow, some here still burn Romo for a very similar situation vs Giants in 2008, 4th down a few ticks on the game clock left and he tried to connect with his WR at the end zone, same result, however some killed him for that but same situation with Dak it is OK.
( PS: I know Romo's was a playoff game after a bye week in Cabo, blah blah blah... but game wise, it was the same situation, last play of the game, no time left on the clock, gotta try the end zone to save the game.)
