Underwood had three catches for a game-high 125 yards and two touchdowns in the 28-14 win, and while he didn't replicate the numbers later in the season that performance was huge for his own confidence.
"I used it as a game that let me know I could do it on this level," said Underwood. "It's not that hard if I keep working at it and pushing myself. I think you can accomplish anything if you work hard at it so I've used that game as a building block. I want to keep it going."
NC State will need Underwood to step up his game this year with the Wolfpack looking to replace T.J. Graham, Steven Howard, and Jay Smith at wide receiver.
"The older guys were all great players," said Underwood. "They were big and could make a lot of plays, and we're smaller but we have great speed.
"We are all quick and able to get out of our breaks fast. We're going to bring a lot of speed to the field. What we're trying to do is take what we've learned from those guys and use it the best way that we can."
Now Underwood, along with Tobais Palmer and Quintin Payton, is one of the "older guys." Redshirt freshmen Hakeem Flowers and Maurice Morgan are looking to learn what they can so they are able to contribute.
"Hakeem and Maurice, they are growing," said Underwood. "They are still learning the plays and trying to take everything one play at a time.
"They are always asking questions... they are just like I was when I first came in, but they are coming around though. I think they are doing real good."
Early buzz at spring practice suggests that Underwood is doing what he can to show that he can be counted on in 2012.
"Bryan is taking a step forward," Wolfpack head coach Tom O'Brien said last week. "He's one guy that really... he had a really good day today. The challenge then is to see if you can do it Thursday. That's what we want.
"He is a different kid this spring than he's been anytime since he's been here. The track thing may have helped his confidence a little bit and academically he is on top of things which we had to pound him a little for in the past. It seems like he has grown up a lot."
I'm just trying to get in the flow of things," said Underwood. "We've been off for about a month so we were eager to get out here. Ever since we came back I've just been trying to bring the energy. I want to keep progressing and get ready for the upcoming season and spring game.
"Every year I've kept trying to figure out what I can improve on. I looked at the previous film and tried to learn whatever I could to make myself better."
A positive for Underwood, and the rest of the offense, is that starting quarterback Mike Glennon is back for his senior season. Glennon passed for 3,054 yards, 31 touchdowns, and just 12 interceptions in his his first year as a starter.
"Mike has made tremendous strides," stated Underwood. "It was a great year for him, but he's always pushing himself... he's not letting up. Every day we got together and threw before spring ball because we're all together with what we want to accomplish. He's not letting up for anybody."
State lost some key pieces at wide receiver, tight end, fullback, and along the line, but the Pack returns the top three tailbacks and four starters along the offensive line.
Underwood believes the Pack's offense can be the strength this fall.
"We have a lot of confidence. We just want to get out and show the world what we can do. We're going to keep pushing and show it on game day."
