Yeah just a bad miss by Dak here. I think the guy played a decent game overall, but this is becoming a common theme for Dak. Not sure if he simply isnt comfortable with the MM offense or what, but if you just pause that at the 6-second mark I'm not sure what Dak is missing there. In an odd way it's almost like it was too easy. The defense didn't disguise anything presnap even. It was a straight cover 2 coverage that you would expect a high school QB to take advantage of as you have the perfect play call on. If the backer runs up the seem with the TE then its an easy connection to the RB in the flat. If the Backer plays his zone as he did the TE is going to have a big window as he did.
Don't make too much out of one pay, but this was a bad miss. Pressure came, but the ball should have been out prior to Dak having to scramble.
