In the 90s...the team would drink sand instead of water...and instead of taking a break from practice they would take a practice from a break...also...they always fought...all day long...they were always punching each other in the face.
They never missed a practice or game because of injury either. They played through all their aches and pains. Actually I don't ever recall an instance in the 90's where a Nebraska player was actually injured, I only recall them injuring every opponent they ever played (they of course injured these opponents because they played harder and were bigger, faster, stronger not because they were dirty)
