Due to both injury and performance, linebacker was a position of flux for the Denver Broncos in 2014. At different times in 2013, the Broncos lined up Von Miller, Wesley Woodyard, Nate Irving, Paris Lenon, and Danny Trevathan as starters. They expect to get Miller, Irving and Trevathan back, but Woodyard and Lenon are both free agents, leaving a potential hole at middle linebacker.

This position is set assuming two things: Von Miller gets healthy, and Von Miller stays clean. After suffering an ACL tear in 2013, Miller has a lot of work to do this offseason. Not only does he have to get back in football shape, in my opinion, he has to get in better shape than he was a year ago. Miller needs to lower his weight and get back to the lean pass-rushing build of his rookie and sophomore seasons in order to improve his production in a critical fourth year of his contract.

Danny Trevathan was a revelation in 2013, and the only player outside of Terrance Knighton who represented a Super Bowl-caliber defense in the Super Bowl for the Broncos. When Von Miller went down, Trevathan went from playing in roughly 70% of Denver's snaps to nearly all of them, and he stepped up to that plate in a big way. Leading the team with 128 tackles in the regular season (41 more than the next player) and 24 tackles in three postseason games, Trevathan netted four forced fumbles and three interceptions in 2013,
