Boise State will begin fall practice on August 5th. They will do so with the same kind of goals and expectations they do every season.

Last season there were some big question marks going into the fall. Quarterback, backup running backs, most of the defense and special teams were all a mystery.

However, it all panned out, and an 11-2 record later, the Broncos are still silencing critics.

In 2013 the question marks are smaller, but they remain nonetheless. The quest to find backup running backs is a seemingly never ending battle, but Boise State is getting a reputation for producing quality rushers.

This season the offensive line and defensive secondary are two of the bigger unknowns. There is considerable talent on the roster in those positions, but can they step it up and get the job done?

Let's look at those possibilities and other key position battles going into fall practice for Boise State.
