Steven M. Sipple: Sleep isn't coming easily for Frost, nor are easy fixes for his Husker program

Nebraska football head coach Scott Frost looks on during the first half against Purdue earlier this month at Ross-Ade Stadium in West Lafayette, Ind.

It's late Friday morning, and Nebraska football coach Scott Frost clutches a Mountain Dew bottle at his desk. He already looks like he's had a long day at Memorial Stadium.

That's what a 4-5 record will do to a highly driven coach, especially after a 4-8 finish the previous season.

I'm guessing one area that keeps Frost up at night is a severe lack of big-play options at the receiver positions.
