Can Nebraska’s defense be good in 2017 despite a change to a 3-4 scheme?

How patient will fans be? Do you buy the transition year for year 3 of Mike Riley or do you still have expectations to compete well nationally?

How long can growing pains last for? Can a truly good DC really overhaul a defensive playbook enough before the season to get things going smoothly? Also, Nate Gerry was listed as nation’s 2nd best safety last year by one outlet….that won’t be easy to replace
