Nebraska hasn't developed its highest ranked recruits, but there have been signs of development.
QB - Noah Vedral, 5.3 2*, developed into a P5 starter despite seeing his completion percentage, yards per attempt, and QBR drop after transferring.
RB - Devine Ozigbo, 5.6 3*, physically looked and played differently under the current staff when he nearly matched his 2015-2017 output (1114 yards rushing) in 2018 (1082 yards rushing on a career high 7.0 yards per carry).
WR - Kade Warner, Unranked, went from walk-on to P5 scholarship holder at multiple universities. JD Spielman, 5.7 3*, had his best season in 2019 and set his career high in touchdowns in 2018 before totalling 5 catches in 3 games with 0 touchdowns in 2020 at TCU.
TE- Jack Stoll, 5.6 3*, turned into an UDFA. Austin Allen, 5.6 3*, went from probable non-contributor to potential NFL contributor.
OL - In 2021 Nebraska had two OLinemen drafted, Brendan Jaimes and Matt Farniok, both 5.7 3*s, in the same draft for the first time since 2009.
DL - Ben Stille and Casey Rogers, both 5.6 3*s, have developed well. Carlos Davis, 5.7 3*, was drafted in 2020.
LB - JoJo Domann, 5.6 3*, has turned into one of the conference's top athletes. Former walk-on Luke Reimer, Unranked Safety, could end up being the best LB Nebraska's had since Lavonte David.
DB - CTB, 5.5 3*, is probably a 2nd day draft candidate today. DiCaprio Bootle, 5.5 3*, led the B1G conference in passes defended in 2018 and is currently on an NFL roster.
ST - Connor Culp, 5.3 2*, won the conference Kicker of the Year honor in 2020 after doing very little over the course of his career at LSU.
Nebraska needs to win some games and hit on some highly ranked recruits, but the current staff's developed some players over the course of their short tenures in Lincoln.
Hopefully Jake Appleget, 5.6 3*, will be another example in a few years.
