STATE COLLEGE, Pa. -- The young and curious are approaching Christian Hackenberg more often these days, peppering the Penn State quarterback with questions about game speed and other topics.

It will slow down, Hackenberg tells his teammates. Just keep working. Everything's going to be alright.

Hackenberg is the reigning Big Ten Freshman of the Year. He's in the spring semester of his freshman year. He celebrated his 19th birthday on Valentine's Day.

He's also a graybeard at Penn State, as crazy as it sounds.

"The guys look at me as one of the older guys, especially the early enrollees," Hackenberg told ESPN.com on Wednesday. "'I still look at myself as the just-turned-19-year-old freshman."

That a Penn State quarterback going through his first spring practice -- remember, Hackenberg was in high school at this time last year -- could be labeled an old guy seemed laughable not long ago. In 2010, Rob Bolden became the first true freshman quarterback at Penn State to start the season opener since Shorty Miller in 1910. Future Nittany Lions coach Rip Engle was four years old at the time. Joe Paterno wouldn't be born for another 16 years.

Now the Lions have had two freshman opening-game starters in four seasons. Hackenberg's accelerated ascent isn't a huge surprise given the hype that surrounded him in high school. Anyone who watched him last season, especially in his final performance in an upset win at Wisconsin on the Badgers' senior day (339 pass yards, 4 TDs, 0 INTs), knew he was no ordinary freshman.

But after starting all 12 games for the Lions in 2013, Hackenberg has both the credentials and the credibility to claim a larger leadership role in an offense facing significant depth challenges along the line and at wide receiver.

"It's tough to try and claim that as a sophomore, but I'm one of the most experienced guys returning on this offense," said Hackenberg, who passed for 2,955 yards with 20 touchdowns and 10 interceptions last fall. "What I went through last year has prepared me to be able to step into that role more than if I would not have played or just played a little bit.

"I'm trying to be a leader through my actions."

His actions this spring include absorbing a new offense described as personnel-driven, pro-style. There are similarities to the system Hackenberg operated under former coach Bill O'Brien, especially the protections and some terminology.

But there's also a lot to learn.

"Some games we may come out in heavy tight end sets, some games we might come out in empty sets," Hackenberg said. "It's more multiple."

Hackenberg boasts the strongest arm in the Big Ten and is lauded for being able to make just about any throw. But it's the simple throws -- the underneath routes, which he "babied" at times last season, or the comeback routes -- where he wants greater consistency.

The 6-foot-4, 220-pound sophomore-to-be has formed a quick connection with new Lions offensive coordinator John Donovan, whose approach reminds him of O'Brien's. Hackenberg also has been in touch with quarterback guru George Whitfield Jr., with whom he worked at the Elite 11 high school camp. Whitfield has tutored other Big Ten quarterbacks such as Michigan State's Connor Cook and Ohio State's Braxton Miller in the offseason.

Nothing is set yet, but if Hackenberg seeks outside assistance, he'd pick Whitfield.

"He's worked with the best of the best the past couple years coming out," Hackenberg said, "so being able to get comparisons to that and see what they did to prepare, that would be good."

Hackenberg also must vary his targets in 2014. Wide receiver Allen Robinson, who had more than three times as many receptions (97) as any other Penn State player last season, is preparing for the NFL draft. There are capable options like tight end Jesse James, who shined during Wednesday's practice, as well as tight ends Kyle Carter and Adam Breneman and wideout Geno Lewis, but none likely can come close to Robinson's production.

"Allen was a guy I really leaned on because I honestly didn't know what to expect a lot of the times last year," Hackenberg said. "I was seeing things for the first time -- going to the Horseshoe for the first time, going against Ohio State’s defense for the first time, seeing Michigan here in a whiteout for the first time. So when you're in those situations, you tend to lean on guys you’ve worked with, and Allen and I worked really hard in the summer together.

"Now I look at myself as filling in Allen's shoes because we have a lot of guys coming in. I just want to be a guy who can help put those guys in situations to succeed. I really want to spread the ball around this year."

New PSU coach James Franklin sees Hackenberg as a smart, demanding player who brings more athleticism to the field that many believe. Hackenberg clocked a 4.7 in the 40-yard dash during Penn State's recent testing.

Franklin and his staff face plenty of challenges on offense, primarily a line with glaring experience and depth issues. But the Lions undoubtedly have their centerpiece.

"He's got a chance to be a special player," Franklin said of Hackenberg. "We're just going to have to keep developing him here over the next three years."

Phase 2 begins this fall.
