The Texas native will likely be one of the biggest story-lines out of the game, with many Nebraska fans wanting to get glimpse of the possible future at the position.
"He's improving," said Nebraska offensive coordinator Tim Beck on Monday. "I think he's a smart guy and picks things up well. He's got to translate it on the field. Once he's seen it once or twice, he's usually good about locking it in his brain. If things are new, sometimes they get him. He hasn't been able to figure out at times, 'I gotta do this or that.'
Beck says one of the biggest things Armstrong is striving for is consistency. Every once in a while, the former four-star quarterback will get upset with himself after mistakes.
"He loses that mojo, he loses that command," Beck said. "He gets mad at himself because he's a competitor. But it shows. You can't do that."
Armstrong, who's progression last fall might have been hampered by a knee surgery midway through the year, has looked injury free through 13 practices.
"I think he's back. I love the way he's running the football," said Beck. "He has a strong arm. He's getting better at knowing where to go with the ball. We just have to keep working with him. Like any young quarterback, he's got fundamentals to work on and decision making things he's got to work on, but he's improving."
When asked what was Armstrong's biggest skill set on the football field, the offensive coordinator took no time to answer.
"His leadership, he's a tough kid," said Beck. "I think the guys know and have a feel when he's in there. It's a different feel and hard to explain. They have a guy with a presence in there."
