The Chiefs have signed 26-year old Ricardo Colclough and 30-year old David Macklin to help out with depth in the secondary and on special teams.  Colclough has played in 36 games (0 starts) in his NFL career and he has made 60 tackles, has 2.5 sacks, defensed 7 passes and intercepted 1 pass.  David Macklin has played in 116 games (75 starts) in his NFL career and he has made 335 tackles, has 1 sack, defensed 54 passes and he has 14 interceptions (including 1 that he returned for a TD).  These were both good moves for the Chiefs as their defense needs all the help it can get.
