For too many years in Denver, the pass rush was something that was either ignored or not given enough TLC. The Broncos tried and tried again to bring in players that could provide a boost (do the names Jarvis Moss or Simeon Rice ring a bell?) but no one was able to provide a consistent pass rush until Elvis Dumervil came around in 2006 and became one of the best pass rushers in team history.
With the addition of Von Miller in 2011 came a complete shift in the way the Broncos built their team, and John Elway knew that the pass rush had to be of critical importance.
