Few games get the juices flowing more than a showdown for first place. Throw in one of sports’ greatest rivalries, and the blood starts percolating.

That’s what we could be in for on Thursday night at Arrowhead Stadium when the Raiders (10-2) visit the Chiefs (9-3) for the AFC West lead.

Going all the way back to the AFL, this is as good a rivalry as the NFL has, and when it has extra meaning — watch out.

Plus, the Chiefs have won four straight against the Raiders.

Bring it on.

“Week 1 we were saying it was the most important thing, and as you get down the line they get bigger and bigger,” Chiefs quarterback Alex Smith says.

“That’s the great thing about this time of the year, the stages get bigger and more meaningful. They save all these division games for the end, so it’ll be fun. We’re looking forward to it. It’ll be an awesome environment on top of a huge rivalry.”

Oakland (No. 3, AP Pro 32) has won six in a row, its last defeat coming at home to KC (No. 4 in AP Pro32). The Raiders are 4-point underdogs at one of the toughest buildings to succeed in, particularly this chilly time of year.

Add in Denver also being a factor in the division …

“It just shows how good our division is,” Raiders quarterback Derek Carr says. “I think it’s a cool thing to be honest. I think it’s awesome. Competition brings the best out of everybody. It’s been like that all year. We’ve all been right there with each other and we’ve all been pushing each other. It’s fun, man.”

More fun for KC on Thursday.
