30-year old inside linebacker Derrick Johnson has been a tackling machine once again in 2012 for the Chiefs.  He has played in 15 games for the Chiefs so far this year and he has 119 tackles, 2 sacks, 11 tackles for a loss, 3 forced fumbles and 2 passes defensed.  Johnson has now played in 121 games in his first 8 years with the Chiefs and he has 758 tackles, 18 sacks, 58 tackles for a loss, 20 forced fumbles, 5 fumble recoveries, 9 interceptions (3 returned for TDs) and 52 passes defensed.  Johnson has really been a late bloomer for the Chiefs as he still seems to be getting better every year.
