3)Broncos outside linebacker Shaquil Barrett has replaced Shane Rayand DeMarcus Ware, while the Denver defense has improved. Barrett's speedy return from a hip injury is one of the biggest reasons why Denver is 2-0, and it's worth wondering if Ray gets his job back when he returns. One of the more intriguing part-time players in the NFL over the last two seasons, Barrett is proving worthy of a full-time role with his rugged game. Nasty against the run with 14 pressures in two weeks against the pass, Barrett is ranked fourth by Pro Football Focus among 3-4 outside linebackers this season. The three men in front of him are AFC West superstars: Khalil Mack, Justin Houston and Von Miller.
