Both B.J. Raji and Letroy Guion may be back in Green Bay for the 2015 season, but with each receiving one-year deals, the Packers did not make a long-term committment to either player.

If the organization is looking for a run-stuffing defensive tackle that will be around for the foreseeable future, they might consider a pair Iowa Hawkeyes in the NFL Draft.

Carl Davis and Louis-Trinca Pasat combined to make the Iowa defensive line a real challenge for opponents to run up the gut the past couple seasons.

"We make each other better," said Trinca-Pasat at the NFL Combine. "When I see him make a play, I want to make the next one, and he feels the same way. If I make a play, he wants to make the next one, so I think competing in that sense has helped us out."

Davis might be a high-round draft choice while Trinca-Pasat is more likely to be a late-round pick, but both players have qualities that should make them valuable contributors at football's next level.

At 6' 5" and 320 lbs., Davis offers rare size that will spark first-round conversation, although there's no guarantee he will go that high.

Despite his frame and stature, Davis unfortunately offered little in the way of pass rush during his college career but displayed potential for more during the week of the Senior Bowl, according to BleacherReport.com's Matt Bowen, who was in attendance for the week of practice in Mobile, Ala. this past January.

"Carl was the best defensive lineman at the Senior Bowl. There's no question about that," said Bowen, a former Packers and Iowa safety. "He was in the backfield all day, every day, winning one-on-one pass rush. He does have the ideal size. ... He played some nose throughout the week, so you're looking at a guy that played the nose, the three-technique, the five-technique in a 3-4, so he's going to give you some versatility."

Of the more than 100 players that took part in the Senior Bowl, Davis was named the Most Outstanding Practice Player of the Week by a panel of NFL scouts, pushing his draft stock higher than ever. And that's great for a player that had just 3.5 sacks and 14.5 tackles for a loss in four years of college football.

Part of the reason for Davis' seeming lack of production was a heavy defensive-line rotation at Iowa, raising questions whether he has either the ability or the desire to be a complete three-down player in the NFL.

Working in Davis' favor, however, is Iowa's reputation of producing players in the trenches on both sides of the football.

As a former NFL offensive line coach, Iowa head man Kirk Ferentz is renowned for developing tackles, guards and centers. Davis would go up against them every day in pracitce, pro talents like Adam Gettis, James Ferentz, Riley Reiff and Brandon Scherff to name a few.

But beyond that, Davis credits Ferentz for the program he runs that extends to both sides of the football.

"Coach Ferentz has been a great help to me, just making sure he's on us day in and day out, talking to us, encouraging us to be the best players we can be," said Davis. "He's not really a dictator. He really tries to guide us along and mold us into men."

The Packers seemingly have a pipeline running from Iowa directly into Lambeau Field, having drafted players like offensive lineman Bryan Bulaga and defensive back Micah Hyde in recent seasons but also defensive lineman Mike Daniels, one of the building blocks of the Green Bay defense.

Even though they're different types of players, Davis looks up to Daniels as a player that commands respect.

"He was a guy, I think he only had two offers from Villanova and Iowa, and to see a guy like that really take off and hold his own future in his hands, he's an impressive guy to watch," said Davis. "Undersized, nobody really looked at him, and he kind of has a chip on his shoulder."

Not coincidentally, Trinca-Pasat is another undersized defensive lineman produced by Iowa at 6' 1" and 290 lbs. He probably won't be the pass-rush threat that Daniels is, but Trinca-Pasat finds ways to overcome a lack of bulk all the same.

"Mike Daniels didn't have measurables either," said Bowen. "Mike Daniels is a pretty good football player, right? There's a certain type of athlete we have at Iowa, a certain of leader, a certain type of work ethic and how they develop and how they take coaching. I think he'll be one of those guys.

"He's not going to be one of the top picks. He's a guy that can be one of those 'glue guys' I call them, those players you have to have on your team that can play a lot of different roles, even play special teams for you."

Trinca-Pasat benefitted from lining up next to Davis, coming up with a big senior season: 69 tackles, 11.5 for a loss, 6.5 sacks. Not bad numbers for an interior rusher.

For his efforts, Trinca-Pasat was also invited to the Senior Bowl. Whereas Davis impressed during the week of practice, his teammate came up big in the game environment with 1.5 of his three tackles ending in a loss of yardage.

Enrolling at Iowa as a 230-pound defensive lineman has prepared Trinca-Pasat well for the transition he's about to make to the NFL.

"Coach (Chris) Doyle and the staff at Iowa, strength staff, has done a good job of helping me do that," said Trinca-Pasat. "It’s a process and I think I had to learn that and understand that I’m not going to get on the field right away. I have to develop first and prove myself at practice before I can become an effective football player."

It's going to be the same in the NFL. Trinca-Pasat is going to have to earn his stripes before an NFL team is going place their unwavering trust in him. And the same goes for Davis.

Whether it's with the Packers or not, Davis and Trinca-Pasat have a lot going for them, coming out of a football program like Iowa.

And perhaps best of all for the Packers, any defensive lineman they spend a draft pick on will come with a very affordable contract of at least four years. That gives the Green Bay some options if Raji and Guion won't be around for the long haul.
