EDITOR’S NOTE: One of a series of profiles on draft prospects who would fit the Broncos’ needs. The Broncos need a center who is comfortable leading from the moment he steps into the team’s facility. Michigan’s Cesar Ruiz may be that guy. He just sounded like a center at the scouting combine. Ruiz File Age: 20 Position: Center College: Michigan Height/weight: 6-3/307 Statistics: Started 31 of 36 games for the Wolverines.
