1. Zac Lee: There were some serious doubts before spring practice at quarterback, but Lee appeared to dispel most of those fears as he replaced Joe Ganz. Lee looked comfortable in his role as starter, passing for 214 yards and three TDs in the spring game. His development over the spring has clearly stamped him as the most likely starter for the Cornhuskers in August when heralded freshman Cody Green will be more comfortable in the offense.
2. Tight ends: Mike McNeill already was one of the conference's most underrated players after breaking the school record for catches at the position last season. But the Cornhuskers will have outstanding depth at the position after strong springs by junior Dreu Young, sophomore Ryan Hill and freshmen Kyle Reed and Ben Cotton. Their growth at the position might lessen some of the worries at wide receiver. Don't be surprised if the Cornhuskers regularly feature two-tight end sets as part of their basic offensive strategy.
3. Antonio Bell: The suspension of Niles Paul was supposed to aggravate the Cornhuskers' iffy depth at wide receiver. But Bell developed into a strong playmaker at the position and even showed some flashes as a kick returner at the spring game. He'll be in the mix for playing time at the start of the season.
1. Wide receiver: The loss of leading 2008 receivers Todd Peterson and Nate Swift robbed the Cornhuskers of much of their big-play capabilities at the position as well as a duo which contributed 125 combined catches last season. It will remain the biggest offensive liability of the Cornhuskers. Players like Menelik Holt and Paul will need to add production. Injury-prone Chris Brooks produced five catches in the spring game and much is expected from heralded junior-college standout Brandon Kinnie. And Marcus Mendoza looks to have adjusted after moving to wide receiver from I-back.
2. Right side of the offensive line: The loss of Matt Slauson and Lydon Murtha robbed the Cornhuskers of solid producers familiar with playing together. Marcel Jones appears to have claimed the starting job at right tackle. And the development of center Mike Caputo allowed Nebraska line coach Barney Cotton to
experiment with moving starting center Jacob Hickman to right guard. But a bigger question will be replacing the veteran leadership they received with Murtha and Slauson over the last several years.
3. Linebackers: The Cornhuskers are talented but very young at linebacker. Colton Koehler and Matthew May both look to have earned starting positions during the spring. Redshirt freshmen Alonzo Whaley, Micah Kreikemeier, Sean Fisher and Will Compton all had their moments. But a key player in fall practice will be Blake Lawrence, who started quickly but suffered a concussion late in the spring.
