The Athletic (paid subscription) ran an article breaking down the 11 recruiting classes from 2009-2019 by rating to see how each school translated those recruiting classes into NFL draftees. Nebraska didn’t have any 5-Star recruits in that time frame, but did sign 67 4-Star recruits. Only 3 of those recruits were drafted out of Nebraska, for an abysmal rate of 4.5%, less than half of second-worst Tennessee.
This is what they had to say:
Nebraska hasn’t recruited as well as the Vols and Longhorns, but the three blue-blood programs that have mostly fallen on hard times the past decade have struggled to develop players. Some of that can be chalked up to coaching turnover in all three cases, but Nebraska signed 67 four-stars in 11 draft classes and produced just three draft picks from that crop. That number was in a league of its own. Comparatively, Minnesota had four four-stars drafted from just 11 four-star signees in the same span.
