All the Pick 6 Previews have listed different numbers from the past that are flattering for Nebraska football…but what position is it most important for Nebraska to build NFL talent at to have consistent success in the B1G?

Is it O-line? Because that’s the area that has dropped off the most since 2000…and needs to be addressed. Or is it another spot?
