Ron Brown.
Coached the most tenacious WR blocking you could ever ask for during the Osborne years, along with some of the greatest tight ends in Husker history.
After being away during the Callahan years, he returned to coach tight ends like Mike McNeil, Dreu Young, Ben Cotton, Jake Long, and Kyler Reed.
Then he switched to coaching running backs and developed Rex Burkhead, Ameer Abdullah, Imani Cross, and Terrell Newby.
Alas, he was let go when Riley brought his guys to Lincoln. Reggie Davis, Brown's replacement, never had a 1000 yard rusher in his 3 seasons.
