I dont think that anything happened, nothing changed. I hate to say it, but I have been saying this for 2 years. The Spring Practice does nothing more than give false hope. The 1's play against the scout team, and instead of pitting 1s v 1s and getting some quality reps.
Check the participation report on Huskers.com for the spring game. It wasn't 1 vs. the others. Even in the TO era it wasn't ever purely #1 defense vs. #1 offense. I remember someone posting that here a while ago. I'll have to search for it.
I agree that the spring game doesn't tell you much, but it isn't just the #1's beating up on the scout team.
