Oregon's Jake Hanson could be the team's best offensive lineman in 2017.

In these breakdowns, we'll aim to explain what's at stake for each position, who the major players are and what do we hope to learn as spring football kicks off on April 5. Today we will focus on Oregon's offensive line.

What we know: The Oregon Ducks lost just one starter from last year's unit and on top of that, the Ducks also get back injured tackle Tyrell Crosby. Oregon also brings back multiple veterans that come with starter experience off the bench. Oregon also has freshman Logan Bathke, Jacob Capra, and Sam Poutasi available after spending the previous fall as redshirts.

Along with multiple starters, the Ducks are welcoming in a new coaching staff and that means a new offensive line coach. Coaching the Ducks this season is Mario Cristobal, an offensive line coach that's thought to be one of the very best in the country.

Who returns: Senior Tyrell Crosby is the headliner of the team and the best pro prospect going into spring football. Behind him, sophomores Brady Aiello, Calvin Throckmorton, Jake Hanson, and Shane Lemieux are all back and all started last season. Seniors Evan Voeller, Jake Pisarcik, and Doug Brenner are all also back and all three started games over their previous three years in Eugene. Sophomore Zach Okun had limited action for the Ducks as a redshirt freshman last year. The Ducks also return four walk-ons who were with the team in 2016.

Who's new: The Ducks signed four players in 2017 that could end up playing along the offensive line at some position. The headliner is top JUCO prospect George Moore, who will contest for starting snaps at either tackle spot. The Ducks also signed freshmen Alex Forsyth, Cody Shear, and Popo Aumavae, the last being a two-way lineman who could also end up playing defensive line for the Ducks.

What's intriguing: How does Oregon shift their offensive line around with the return of Crosby? The Ducks started Brady Aiello in his place last year and then used Calvin Throckmorton at right tackle. Does Oregon shift one of the sophomores into the guard spot that is opened up after Cameron Hunt's graduation? Or, does Oregon look at Crosby and ask him to slide into a guard spot? There's also the question of George Moore and where he fits into the mix. A clear tackle, is he good enough to push one of the other sophomores out of the starting lineup?

The entire offensive line could really see some shifting and moving with the hire of Mario Cristobal as the offensive line coach. The Ducks are expected to use more of a power-zone offensive approach, which changes a little bit of the team's blocking schemes. How well will Oregon pick it up? What player changes come with that?

What we hope to learn this spring: Finding out the exact order of a starting lineup doesn't seem logical or smart for summer development, but getting an idea of who can contribute and who's in a position to be a role player at best is the goal. Locating Oregon's top eight to ten offensive lineman will be the goal and what Oregon hopes to find out after 15 spring practices. Finding out who is also the team's back-up center will be key. Is it Doug Brenner or Zach Okun?

One other question with this group is the physical growth they've made in the weight room since the end of the season.

DuckTeritory's pick: The Ducks will emerge from spring football with an idea of where George Moore fits within the offensive line and also know if they need to shift Tyrell Crosby from outside to inside the offensive line.
