NCF Nation: Cliff Avril

WEST LAFAYETTE, Ind. -- Purdue's reputation for producing great quarterbacks is recognized throughout college football, as names like Brees, Griese, Herrmann, Dawson and Everett are linked to the program.

But there's another position where Purdue has put together a similar track record of excellence: defensive end. The Boilers' D-end tradition isn't as well-known as its quarterback heritage, but consider the names who have come through the program in the past two decades: Roosevelt Colvin, Chike Okeafor, Akin Ayodele, Shaun Phillips, Ray Edwards, Rob Ninkovich, Cliff Avril, Anthony Spencer and Ryan Kerrigan, the 2010 Big Ten Defensive Player of the Year and a unanimous All-American.

All nine players went on to the NFL, and several like Kerrigan and Spencer are in starring roles. Purdue has called itself the Cradle of Quarterbacks for years. It now also uses the label Den of Defensive Ends.

Boilers junior defensive end Ryan Russell needs no education on the subject.

"Very aware," Russell told ESPN.com. "A lot of those guys come back, Roosevelt Colvin, I had a chance to talk to Cliff Avril when we went to the Little Caesars [Pizza] Bowl in Detroit. I knew Ryan Kerrigan and he came back and talked to us.

"It's a big tradition, and I'm hoping definitely to uphold it."

After losing defensive tackle Kawann Short, a second-round pick in last month's NFL draft, Purdue is looking for the next star to emerge along a line that underperformed in 2012. The Boilers finished 78th nationally in both rush yards allowed (182.3 YPG) and sacks recorded (1.69 per game).

Along with veteran defensive tackle Bruce Gaston, Russell is viewed as a potential major contributor up front this fall. The 6-foot-5, 275-pound junior will enter his third season as a starter and his first under Purdue's new coaching staff. After recording 33 tackles and making 11 starts as a redshirt freshman in 2011, Russell had 37 tackles, including 8.5 for loss and four sacks, last season.

"He’s got a power-to-speed ratio that's good for him to be a factor," defensive coordinator Greg Hudson said. "He can play the run, but he's got that end build and speed where he can also affect the passer.

"He's got that prototype look and ability."

Russell might look the part, but like many of his teammates, he needs to get stronger. His speed and lower-body strength are in good shape, and he has fully recovered from knee and ankle injuries, but his upper body "isn’t really where I would like it to be."

After practicing alongside Kerrigan as a true freshman in 2010, Russell understands the gains he needs to make.

"Ryan Kerrigan was one of the strongest people I've ever met," Russell said, "so when that's the standard with the Big Ten, Purdue defensive linemen and defensive ends, we definitely and myself personally have a long way to go."

Kerrigan led the country in tackles for loss (26) in 2010, finished third in sacks (12.5) and tied for second in forced fumbles (5). Russell observed firsthand the relentless motor that drove the Boilers' star.

When one pass-rush move didn't work, Kerrigan would simply move to the next and the next until the whistle blew.

"Pass-rushing a lot of the time is a mentality, going 110 percent, outworking somebody all the time, every play," Russell said. "[Defensive line coach Rubin Carter] always says, 'If you're not going to make the play, they will.' So just always having that mentality that you’re going to get there is a big thing.

"Your get-off and your motor is the engine that runs the train."

Russell is taking well to the new staff, the faster practice pace and the new defensive scheme under Hudson. He has worked extensively with Carter, a former longtime NFL assistant, on using his hands more effectively to fend off offensive linemen.

Hudson, who last season had a front-row seat for one of the nation's best defensive lines as a Florida State defensive assistant, shapes his system around Russell and the other down linemen.

"We will do things to turn him loose," Hudson said. "We cater to the D-line. We're going to make sure they know what’s going on, there's no confusion and they're happy. And when the ball's snapped, we say, 'Take off, break off.'

"That's what we want them to do."

Russell continues to follow Kerrigan with the Washington Redskins, and he also studies the other Purdue greats he has met like Avril (Seattle Seahawks), Ninkovich (New England Patriots) and Spencer (Dallas Cowboys).

"You have a common ground," Russell said. "They started the same place you started, and what they're doing is the goal, so you’re trying to see what they're doing to get to the goal you all share."
