One of the buzz words that keeps cropping up in Kansas City Chiefs circles this spring is "culture," which is strange, because "culture" is not a defensive kind of word.

"Savage" and "relentless" and "heat-seeking" are defensive kind of words, best uttered by the likes of a Facenda or a Kalas. "Culture?" "Culture" is something they brag about at Wimbledon.

"One of the things that we've really tried to get everybody to understand is that we're trying to develop a certain type of culture here," new Chiefs defensive coordinator Bob Sutton allowed this week. "Not only how we do something, but the way we do it."

You tend to get quite a few indirect jabs and read-between-the-lines quotes when there's a regime change, especially one as pronounced as the broom Clark Hunt used to sweep away 2012. But one keeps cropping up, over and over the past five weeks of minicamps and Organized Team Acitivies:

Grandpa Romeo was soft.

No one will just come out and say that, of course. Everybody liked Romeo Crennel, personally, as a coach and a defensive play-caller. Grandpa Romeo was level-headed, paternal, and downright cuddly, up close. In the right position, on the right staff, with the right locker room, he fits. When too many kids take too much advantage of those long leashes, though, well — we don't have to tell you what 2-14 looks like.

"The (new) guys come from systems where they attacked," outside linebacker Tamba Hali explained. "Nothing against our old system, but they (weren't) attacking."

"I mean, just any way we can disrupt," defensive tackle Dontari Poe allowed. "Disrupt the defense, disrupt the quarterback, getting our hands up."

The 2013 Chiefs want to be a hard defensive team. Hard, hard, hard. Hard to prepare for, hard to simulate, hard to play, hard to recover from.

Over the past seven seasons with the New York Jets, three as coordinator and four as linebackers coach, Sutton's defenses ranked 14th in the NFL in takeaways and 13th in points allowed.
