There was pass credited as a drop by Cooper where he had to stop his momentum going across the field and reach to his back-shoulder for the ball. The ball hit his left hand and shoulder before his right hand could get there to establish control. Many were all over Cooper for that play, but I maintain that it was a poor pass. Instead of leading the receiver when he was clearly going at full sprint across the field, Prescott forced him to go against his body, which is why he couldn't get his right hand over. He technically got two hands on the ball, but not at the same exact time.
We had a few others similar to that as Dak struggled with that throw for some reason last year.
