Brett Hundley took the snap from center and dropped back with every intention of throwing the football downfield. It was first and 10 and the Green Bay Packers were 23 yards away from scoring on their opening possession against the Detroit Lions. Hundley had gotten a clue that it was man-to-man coverage because safety Tavon Wilson followed tight end Lance Kendricks from the left side of the formation to the right, leaving Davante Adams and Jordy Nelson to the left. Hundley faked the handoff to running back Aaron Jones and then turned his attention to Nelson running free down the seam after putting a move on slot cornerback Quandre Diggs that caused him to fall. Safety Glover Quin was in the middle of the field but looking the other direction. Nelson raised his arm to indicate he was wide open. Boom. Touchdown, right? Nope. Hundley, perhaps catching out of the corner of his eye linebacker Tamir Whitehead slipping Jones’ block, didn’t deliver the ball. He stared at Nelson but didn’t throw it, choosing instead to pull it down and run. He was sacked for a 2-yard loss. This was not an isolated play in the 30-17 loss to the Lions on Monday night.
