I watched the team practice during the Husker Youth Experience last Saturday. I had two boys attending.
We probably watched them practice for 20 to 25 minutes. They were moving through plays very quickly. No idle chat between plays. All four quarterbacks rotated in.
Granted, it was a short practice, but I left the practice very impressed with Witt. Ganz and Davis looked pretty good, too. I'm pretty sure that Keller threw two picks.
I don't know how Witt would do with 80,000 people watching him, but I wouldn't write him off for this year. I think he's the real deal.
