Last game, even though it was a loss, Dak only got loopy on one play- the screen pass/lateral he threw under pressure.
But the rest of the game, Dak looked like a quarterback. He didn't get happy feet and throw the errant interceptions he usually does when he gets nervous.
The interceptions he threw were because the receivers were tightly covered and the bounce went against the Cowboys. The Lions were sitting on the slant routes because they knew the Cowboys like them.
That's on the coaching, not Dak.
If he can keep his poise the Cowboys might actually win a game against a good team.
