It would quickly turn from a practice into a competitive game, thus negating the whole purpose.
But the spring game isn't the only scrimmage we can have. Nothing would stop us from having all the scrimmages we want. Add a couple of more practices to the spring and hold the exhibition game a week later.
I'll be at the game tomorrow. And I and my family are sure to have a great time. But it would sure help me get my Husker football fix if we were actually matched up against another team. Do you have any idea how hard it is to get from January to September without a true Husker football fix!?! And after all, it is all about
my needs, isn't it?

The thing is, once it turns competitive, that's when jobs and incentives come into play. That's when ticket prices get jacked up.
I completely understand your point; I'm a competitive person at heart. If we're going scrimmage against other teams, they need to be closed door, controlled types of settings to avoid them getting out of control.
