Chiefs signed ILB Brandon Siler, formerly of the Chargers. Just 25 years old, Siler made 12 starts over the past two seasons in San Diego, racking up 111 tackles, three sacks, and two interceptions. Per Pro Football Focus' ratings, Siler graded out positively as both an inside pass rusher and cover 'backer last year. He also had seven special teams tackles in 2010 and should push for snaps immediately next to Derrick Johnson.
