Nebraska coach Scott Frost has seen success. He had plenty of success as a player. And, as a coach, success has followed him as well.

Frost turned UCF around very quickly. It took only two years for him to make the Knights a perfect team — from an overall record perspective anyway.

At Nebraska, he hasn’t had the same level of success. In Year 1, the Huskers went 4-8 under Frost. As of now, they’re 4-6.

So, what’s the difference? Maybe at UCF, players got more sleep.

Well, at least according to Frost, sleep is extremely important:

We’ve all read and heard what a good night’s rest can do for you. It is important. Is it the biggest indicator to performance on the field?

Maybe. Maybe Frost knows the ultimate key to success.

Just get some “Z’s.”
