On Monday, Nebraska started spring practice in its second year under head coach Scott Frost. Unseasonably frigid temperatures kept work inside as the squad opened preparation for the Spring Game on April 13.

This is now Nebraska’s second straight season without a bowl game, meaning a second long winter of waiting for Nebraska football. So spring practice should bring a welcome relief for Nebraska fans weathering yet another cold winter of discontent. Here’s what to keep an eye on as spring practice begins.

OFFENSE

Returning Strengths

• Quarterback. There is little doubt that Adrian Martinez is the biggest reason for Nebraska’s optimism in 2019. Martinez’s accomplishments last season have at least one Las Vegas sports book listing him as third-favorite for the Heisman next year. That might be a little optimistic, but at least Nebraska is coming into next year’s campaign with its situation at signal-caller settled.
• Y and Z Receivers. JD Spielman is clearly Nebraska’s most dangerous receiving threat returning next season, and incoming freshman Wandale Robinson looks perfectly set to excel in the slot. While not every receiving position is clear (see infra), Nebraska does have a lot to lean on at receiver.
• Tight End. Jack Stoll could very well be one of the team leaders next season, and Kurt Rafdal and Austin Allen both saw increased playing time towards the end of 2018. Kateriene Legrone should also have an opportunity to see the field, giving Nebraska at least four dangerous options to create mismatch opportunities and challenge the middle of the field.

Biggest Questions

• Offensive Line. Nebraska does have quite a bit of returning talent, but it’s not entirely certain how it is going to fit together. And center for Nebraska is one of the biggest open questions, which is always a challenge. There’s enough talent for Nebraska’s offensive line to be successful, but it is still unproven.
• X Receiver. Nebraska will be looking for a true no. 1, go-to receiver to make catches that get first downs as well as threaten downfield. Stanley Morgan’s leadership and production will be a huge challenge for Nebraska to replace, and while there is significant depth at receiver, it is unclear who (if any) in that room will be able to fill that role.
• Running Back. At this time last year, it was hard to imagine that Devine Ozigbo’s graduation would be one of Nebraska’s biggest challenges going into 2019, but here we are. Maurice Washington and Miles Jones, Nebraska’s two returning backs with any playing time from 2018, are huge question marks for different reasons. The incoming backs, Dedrick Mills, Rahmir Johnson, and Ronald Thompkins, all have potential but are unproven.

Players to Watch

• Jaylin Bradley. Ozigbo is gone. The competition for running back carries won’t arrive until fall camp. So this spring, Bradley will be competing with Wyatt Mazour and the other walk-on running backs for a chance to get the carries that Ozigbo had last year. Bradley didn’t see the field last year, and with the other backs coming, this spring may be Bradley’s last, best chance to really make an impact and earn a spot on the depth chart.
• Cameron Jurgens. One of the biggest open positions for Nebraska in 2019 is center, and Jurgens has taken a strange path to the position. Jurgens was a four-star prospect in Nebraska’s 2018 class (.9227 composite, according to 247 Sports) – as a tight end. But after a redshirt year, Jurgens switched positions from tight end to offensive line and looks to be competing for a spot at center. Given his composite ranking, Jurgens’ athletic prowess is unquestioned. If he can make the switch in positions – and make no mistake, it’s a massive switch – then Nebraska could get a quick infusion of talent in the middle of the offensive line.
• Jaevon McQuitty. Much like with Bradley, there is an opening in the depth chart at X receiver, and McQuitty has his best opportunity to take advantage and seize a spot. He’ll have some competition from players like Mike Williams and Andre Hunt, in addition to the freshmen receivers coming in the fall. So this spring is the time for McQuitty to make his move, if it’s going to happen.

DEFENSE

Returning Strengths

• Defensive Line. The returning experience is there. Particularly with the addition of graduate transfer Darrion Daniels, Nebraska front should have both experience and depth coming back. The production of that front last year, of course, wasn’t what anyone thought (no. 96 nationally in rush defense and no. 76 nationally in sacks, according to com). But after a year in defensive coordinator Erik Chinander’s system (and, in all candor, a year removed from former defensive coordinator Bob Diaco), perhaps the unit we thought would be a strength in 2018 will actually become one in 2019.
• Secondary Starters. Three of Nebraska’s four starters in the secondary should be decided going into spring football. Dicaprio Bootle was Nebraska’s best and most consistent cornerback throughout 2018, and Lamar Jackson responded to his benching early in the season to solidify himself as a starter. At safety, neither starter returns, but Deontai Williams showed such athleticism and natural ability that it would be stunning not to see him on the top line of the depth chart this year.
• Mohammed Barry. Martinez is arguably Nebraska’s most important player, but it’s hard to overstate the leadership Barry brings not only to the defense but to the team in general. With a number of Nebraska’s vocal leaders from last season graduating, the mantle looks to fall to Barry to take on that role in 2019.

Biggest Questions

• Secondary Depth. After the three likely starters, there’s little proven talent in the secondary. There is a tremendous amount of potential, but all unproven. That should be enough to keep Chinander up at night, but also provides an opportunity for someone to stand out.
• Pass Rush. A pass rush is a defensive back’s best friend, and Nebraska’s pass rush struggled last season. With no obvious pass rush specialist being recruited in this year’s class, Nebraska will be looking to manufacture a rush from the talent already on the roster. A healthy JoJo Doman staying at outside linebacker should help, and a return to 2017 form for Ben Stille may be part of the answer.
• Run Defense. Take another look at Nebraska’s performance against teams like Wisconsin and Iowa – if you can stomach it. Wisconsin averaged 7.7 yards per carry against Nebraska, while Iowa averaged 5.5 yards per carry. Nebraska simply will be able to win the B1G West if it cannot significantly improve how it defends power running teams.

Players to Watch

• Breon Dixon. After transferring from Mississippi, last year it looked like Dixon might be the kind of immediate infusion of SEC talent that could give Nebraska’s defense an instant jolt. But it didn’t happen for Dixon last year, who saw very little of the field and was unable to make an impact. With a year in the system, 2019 is the time for Dixon to make his move.
• Avery Anderson/Eric Lee. Yeah, I know it’s cheating to list two guys here. But Anderson and Lee were both highly regarded recruits, now in their last year at Nebraska. With the questions remaining about depth in the secondary, these two seniors have a door open to see the field and leave an impact in 2019.
• Collin Miller. Will Honas came in as a junior college transfer last year and looked to be part of the puzzle for Nebraska’s transition on defense. But an injury against Purdue knocked Honas out for the season, and is still recovering from that injury. So outside of incoming freshman Jackson Hannah, Miller has the opportunity this spring to solidify a starting position at inside linebacker.

GBR, baby.
