Kansas City's defensive production shows little need for change among its coaching staff. While Pepper Johnson might want to bring a person or two over, odds are good that the Chiefs won't experience much turnover.
After all, this is Romeo Crennel's staff to start with.
Defensive Line Coach: Chiefs Defensive Line Coach Anthony Pleasant
Kansas City's top defensive line draft picks haven't quite panned out as well as intended. Tyson Jackson flashed a couple times in the 3-4 end position he's a prototypical fit for. Glenn Dorsey performs as a steady but unspectacular presence on the other side. Dorsey was initially drafted as a 4-3 defensive tackle, though, and would likely do better there.
This isn't a glowing recommendation for Pleasant. However, a number of other talents on the team blossomed nicely under Pleasant's watch. Wallace Gilberry provides a nice burst of pressure in spot work on passing situations, while journeyman Amon Gordon might have found a niche on Kansas City's line.
The Chiefs are Gordon's eighth NFL team in nine years. His 18 tackles this year are better than a third of his career totals. His two sacks this season are the only sacks of his career.
If Pleasant can coax this type of production out of Gordon, he should do well developing talent like Allen Bailey and Jerrell Powe. Bringing Johnson in as coordinator should only increase his success.
Linebackers Coach: Chiefs Linebackers Coach Gary Gibbs
The emergence of marquis players in the Chiefs linebacker corps doesn't seem to end. First, Tamba Hali makes an amazing transition from end to linebacker.
Already a relentless, high-motor player, Hali developed into a pass-rushing beast. Hali's posted 35 sacks and 12 forced fumbles in the last three years.
Then Derrick Johnson started realizing his potential. Miscast initially as an outside linebacker, Johnson returned to the middle and became the NFL version of the sideline-to-sideline defender fans watched during his college days.
Now, Kansas City has another linebacker coming into his own with Justin Houston. Houston has already made great strides elevating his game to the professional level, and should provide that second pass-rusher needed to make Hali truly devastating.
Gibbs has plenty of talent to work with, but under him this group has gone from solid to elite. There's no reason to mess with something that works this well.
Secondary Coach: Chiefs Secondary Coach Emmitt Thomas
Two years ago, I wrote how Emmitt Thomas coaching for Kansas City made too much sense to not happen.
Today, I feel much the same way.
Kansas City's secondary boasts a pair of defenders who were practically can't-miss prospects. Scouts and coaches expected Brandon Flowers and Eric Berry to do well at the next level.
The same can't necessarily be said of their other two starters in the secondary. The Chiefs selected both Brandon Carr and Kendrick Lewis in the fifth round. Carr took some time to adjust from the Cover 2 defense the Chiefs drafted him to play, but has since paired well with Flowers as a formidable corner tandem.
Lewis debuted with three interceptions in his rookie season, and has three more again this year. However, his overall played has stood out more with Berry out for the season with an ACL tear.
Kansas City hasn't had this type of secondary in two decades, with young, solid performers at every position. Thomas has them playing well even despite losing Berry.
There's nothing to fix here, and no team more appropriate for Thomas to finish his coaching career.
