Christian Hackenberg completed all but a handful of his 60 passes before breezing out of Penn State's pro day.

The former Nittany Lions quarterback didn't stop to talk to local media Thursday at Holuba Hall, instead choosing to let his on-field performance in front of scouts from 31 of 32 NFL teams - all except the Falcons - speak for itself."I honestly think it was an A," Hackenberg's coach Jordan Palmer said. "He spun the ball really, really well, which was something that there were questions on coming off the tape. I thought he was really on balance, really smooth. … Threw some really good deep balls as well."The general response was people were really pleased with the accuracy. The ball was right up on the receiver's face," Palmer said. "The ones that he missed were a little here, a little there. But they were definitely catchable balls."Hackenberg, 6-foot-4, 223 pounds, has been training with the quarterbacks coach in California since after January's TaxSlayer Bowl. He's fresh off some of the top performances for quarterbacks in the 40-yard dash (4.78 seconds) and three-cone drill (7.04 seconds) at February's NFL Scouting Combine.At pro day, he ran nine different play options, which Palmer said is about as many as in an NFL system. Consistency was the goal, Palmer said, as Hackenberg's completion percentage had been a concern coming out of college (he completed only 53.5 percent of his passes last season).And with only a few miscues Thursday, Palmer said Hackenberg is peaking at the right time and could start contributing right away in the NFL.Former Penn State wide receiver Derek Moye, who caught for Hackenberg, said the quarterback "was slinging the ball.""You could tell he's pretty cool and calm. I think as an NFL quarterback, that's a good quality, a good trait to have," Moye said. "You can definitely tell that he has all the tools and has the arm strength to be a really good quarterback in the NFL."Former Penn State center Angelo Mangiro snapped for Hackenberg and said he saw firsthand this week how dedicated the quarterback has been to the draft process."He woke up at, like, 5:30, 5:45 every day to start his training process, and he's worked extremely hard," Mangiro said. "He's lost weight, lost body fat. He did an awesome job, and you can tell by the way he looks. His balls came out real crisp today. So I'm happy for him, proud of the guy."With the draft a little more than a month away, much of Hackenberg's work is done. But Palmer said this pro day performance will do a lot to raise his profile even more."You're going to start to hear a buzz nationally," Palmer said, "of Christian Hackenberg trending upward."Comfort zoneDefensive players Carl Nassib, Austin Johnson, Anthony Zettel and Jordan Lucas were the other former Penn State players at pro day who also worked out at the combine. Johnson said being in familiar territory with his fellow defensive linemen Nassib and Zettel was a welcome change."Being here with my boys again, just having them push me, and everybody push each other," Johnson said. "We were all in our comfort zone. I feel like we all did pretty well today."Nassib said he's enjoyed the past few months preparing for the draft, especially since he has gone from unknown walk-on to NFL prospect."It's been awesome just meeting so many gurus and awesome smart guys who just love football," Nassib said. "And I love talking football, so it's been a lot of fun."Zettel said the combine was uptight with everyone running on such little sleep, and pro day was a more relaxed environment. He said he felt great and wished he had felt this good during the season.Safety Jordan Lucas endured a season-ending injury in November, missing most of the combine because of it, and said it has been "annoying" to deal with a recovery process that was sometimes slower than he would like."I'm a competitor, so I wanted to get back out there," Lucas said. "I wanted to train hard, and I had some limitations at first, but I'm back full go now. And that's the best thing I can ask for."While the combine players were used to having big league scouts around, Mangiro, 6-foot-3, 321 pounds, said he was nervous during his measurements when he first encountered the NFL personnel."I blacked out," he said "That was the first time in front of scouts."I was sucking it in."
