With Campbell's amazing combination of size and athleticism, he's likely to vault ahead of USC's Charles Brown and into a top-20 or even a top-15 pick.
That's good news for the Packers. Campbell started just 17 games in his collegiate career and never even was named an honorable mention on the all-ACC team.
With Chad Clifton coming off an injury-plagued season and turning 34 in June, the Packers badly need a left tackle — and Brown appears to be an excellent fit. Brown figures to be available when the Packers are on the clock with the 23rd selection — subject to change, of course, with eight weeks until the draft. He met with the Packers at the Scouting Combine, a source told Packer Report.
Brown (6-5, 303) was recruited as a tight end before being moved to left tackle during the middle of his redshirt freshman season. He protected the blind side for two seasons and as a senior won the Morris Trophy, which is awarded to the Pac-10's best offensive lineman and is voted on by the league's starting defensive linemen.
The move to left tackle came "pretty natural," Brown told reporters at the Combine. "I had a lot of work to do, though. (USC offensive line) Coach (Pat) Ruel helped me out with that."
Ruel, who was an assistant offensive line coach for the Packers during their 2001 and 2002 playoff seasons, did fine work. Brown said he hasn't allowed a sack since the fourth game of the 2008 season, to Oregon's Nick Reed (now with the Seahawks). His pass-blocking ability is a byproduct of his athletic ability — obvious from his tight end roots — and long arms.
It helps that he's been tested regularly at practice. He was teammates with Clay Matthews III — the Packers' relentless Pro Bowl rookie — and Everson Griffin, an early-round prospect who recorded eight sacks and nine tackles for losses in 2009.
"They helped me out a lot," he said. "Everson and Clay are the best D-ends I have ever seen in college. I got to see them every day in practice so it made me a lot better."
Brown said he's been working on his run blocking, with an emphasis on keeping his hands and feet moving, but would arrive in Green Bay with the advantage of being well-versed in a zone blocking scheme.
Brown recognizes that he needs to get stronger, and a year watching and learning behind Clifton should help Brown accomplish that. When the Packers drafted Clifton, he was 6-foot-5 and 329 pounds. That's 26 pounds more than Brown. Clifton was listed as 6-foot-5 and 320 pounds in 2009.
"Yeah I definitely could (add weight)," Brown said. "I just didn't have any money at SC to pay for my meals. One meal a day."
Brown is not a great run blocker, but Clifton never has been great in the run game, either. Left tackles make their money by keeping their quarterback upright, and that will be the priority in Green Bay as long as Aaron Rodgers is the franchise quarterback.
Brown seemed to recognize that when asked what his NFL team will get on draft day.
"They will get a real good pass-protector."
