1. Grant Wistrom - 1,125 votes (32.3%)
Grant Wistrom emerged as the face of the vaunted Blackshirt defense during Nebraska's dominant run in the mid-1990s, where he helped lead the Huskers to three national titles and a 49-2 record during his career.
The school's all-time leader in career tackles for loss (58.5), Wistrom was a two-time first-team All-American and a three-time all-conference selection.
He was also a two-time Big 12 Defensive Player of the Year and took home the Lombardi Trophy as a senior in 1997.
Wistrom was just as successful in the classroom, winning to the NCAA Today's Top Eight Award for academics.
He was the No. 6 overall pick by the St. Louis Rams, earning a Super Bowl ring in 2000 along with two other Super Bowl appearances during his nine NFL seasons with the Rams and the Seattle Seahawks.
2. Trev Alberts - 727 votes (20.9%)
Nebraska's first ever Butkus Award winner, Trev Alberts is widely regarded as one of the best defensive players in school history.
After a breakout junior year in 1992 where he earned first-team All-Big Eight and second-team All-America honors, Alberts put together one of the best individual seasons ever by a Husker defender as a senior in '93.
In leading NU to a perfect regular season and a berth in the national championship game, the Big Eight Defensive Player of the Year led the team with 96 tackles and tied the school record with 15 sacks.
Alberts was also given the NCAA's highest academic honor by being named to the Today's Top Six, and his No. 34 jersey was retired by Nebraska in 1994.
He was later taken by the Indianapolis Colts with the fifth overall pick in the '94 NFL Draft. After a three-year professional career and a stint as a college football analyst for ESPN, Alberts was eventually named athletic director at Nebraska-Omaha in 2009.
3. Neil Smith - 616 votes (17.7%)
One of the most dominant defensive linemen of his generation, Neil Smith was a first-team All-American selection in 1987 at the defensive tackle position in Nebraska's 5-2 defensive front, which essentially translated to an end in a modern 3-4 scheme.
Smith ended his career with 133 total tackles, including 14.5 sacks and 26 tackles for loss.
He was taken as the second overall pick by the Kansas City Chiefs in the 1986 NFL Draft, where he would go on to be a six-time Pro Bowler and four-time All-Pro during his 13-year NFL career.
Smith capped it off by earning two Super Bowl rings with the Denver Broncos in 1998 and '99.
Smith's 104.5 career sacks rank 25th on the NFL's all-time list, and he was inducted into the Chiefs' Hall of Fame in 2006.
