Having multiple backs with varying talents keeps defenses off balance, and it provides fresh legs throughout the game. It does water down the numbers for any one back, which could be a drawback for them personally, however.

Nebraska has too many very good running backs to leave off of the field. RB by committee at the start of the season will help to determine who that main back should be!

I do not believe there is one back is ready to be all things. But by mid year there may be one.

Until one of the RB steps up and is a clear favorite I think the best option is to use the talent you have. They can all complement each other.
