Ultimately, no surprise he had to exhibit confidence in Hundley. He never really did. From the 10in the 4th two stupid runs to the left just giving the ball back. Hundley had to complete a pass there. Other examples abound. At the end, again stupid clock management there was, arguably a fumble recovered by the Pack: the ball was moving in the runners hands so when he hit the ground maybe he wasn't in possession. Regardless, I challenge would have had the same effect as a TO, which he had to call anyway to preserve time. So the challenge was a freebie. Hundley's got a chance but keeping him in a lockbox isn't going to work.
