Which players in the 2017 class have to succeed at Nebraska in order for the class to be considered a success years down the road?
This is more than simply ranking the players best to worst, though. Consider the implications of the player's position and recruiting location, and what it will mean to the team's future recruiting efforts if (for example) they pull a highly touted player from the coast but are unable to turn him into a high-caliber player.
In no particular order, Avery Roberts, Tyjon Lindsey, and Guy Thomas stand out as players who I think are pretty critical to future success.
