AM isn't executing at the level needed to make this offense click. Sure, there are quite a few things that don't help - bad snaps, poor line play, etc. But, Nebraska had open WR's today. Guys with a half a step to a step on their defender. He either couldn't see them, didn't have the confidence to make the throw, or just missed the throw entirely. And it's been that story for four years now. It was excusable as a true freshman and even as a sophomore, but not so much as a senior. We're also talking about a guy that got benched as a junior because of his struggles.
Nebraska doesn't need an elite QB there, but they need better than what AM has to offer... full stop. It's just not good enough.
