Dak made some plays, and missed a few big ones. There were a few times he should've tried to audible when the defensive formations were bad match-ups for the play calls.
The endzone fumble isn't really excusable. He should've thrown it away or tucked it and taken the sack outside of the end zone. Trust Chris Jones to get a good punt with the wind at his back.
However, with a better game plan from the coaches, and more discipline from the team with just a few less penalties, he played well enough to win. He shares the blame, but I put more on the O-linemen committing holding calls that killed drives.
