The lockout might delay the progress of many rookies around the NFL, but we hear the Broncos have no doubts that OLB Von Miller is capable of being a starter from Day One. Miller, who was the second overall pick in the draft, is expected to provide an instant boost to a Denver defense that struggled to get pressure on the quarterback in 2010. The Broncos are thin at linebacker after moving both Elvis Dumervil and Robert Ayers to defensive end, and will need Miller to be effective to improve a defense that ranked 32nd in the league last season. One issue with Miller's progression could be his adjustment to a 4-3 scheme after playing in a 3-4 defense at Texas A&M, but a source close to the team told PFW that Miller was able to secure a playbook and that he understands what is expected of him in that style of defense. Miller also has been working with former Aggies and Cowboys LB Dat Nguyen, who played in a 4-3 in the NFL and is now an inside linebackers coach at Texas A&M.
