Raider hater. If you’re a Broncos fan, you hate the Raiders on a level akin to someone that did something terrible to your family. The Chiefs are just a division rival. To be a Broncos fan is to unconditionally revile the Raiders.

— Sam, Denver

Kiz: Can new Broncos running back Jamaal Charles add juice to the Denver offense or infuse juice into a sedated rivalry with the Kansas City Chiefs? I’m betting not. Running backs age in dog years. If Charles’ battered knees hold up to play against his old team on Oct. 30, I will consider it a bonus. Hating the Raiders is the oldest football tradition in Denver, while Broncomaniacs would put the Chiefs in a headlock, give them noogies, then invite them all to Christmas dinner.

Yuletide visitor. I can confirm there was a Chiefs fan at our Christmas dinner.

— S.G., rockin’ the Rocky Mountains

Kiz: The Raiders are Darth Vader. The Chiefs are Ned Flanders.

Silver ‘n’ black smack. A Raiders fan is the kid on my high-school football team that who didn’t know if we were on offense or defense but liked to wear his jersey to class on Fridays.

— W.G.P., deep in the woods

Kiz: If I’m not mistaken, that kid’s name was John Matuszak (God rest his soul).

Second guessing. I am unable to understand why John Elway would trade Kapri Bibbs, a young and dynamic running back, then sign Charles, an over-the-hill back plagued by injuries.

— Donald, befuddled in Broncos Country

Kiz: There are not enough touches in the backfield to keep C.J. Anderson, Devontae Booker and Charles happy. Elway, however, knows at least one of them is very likely to break down. So Elway is diversifying his bets, hoping the sum of their parts somehow gives the Broncos one running back as dangerous as Christian McCaffrey.

Firing shots. That was a nice column you wrote about the incompetence of the Denver teams owned by the Kroenke family. But you left out Arsenal, which has been in steady decline since Kroenke bought the English Premier League club.

— Glenn, Gunner at heart

Kiz: As any fan of the English Premier League could tell you, Kroenke is a dirty word in North London. And his NFL team is a wreck that has washed up on the beach in Southern California. But Arsenal and the Rams are not my problem. So get off my back, OK? The hard-working staff here at Kickin’ It Headquarters has its hands full trying to fix the Nuggets, Avalanche and Rapids. As Scotty, the great philosopher/engineer from “Star Trek,” was known to say: “I’m giv’n her all she’s got, Captain. An’ I canna give her no more.”

And today’s parting shot is a snappy retort to my steadfast belief new San Francisco linebacker Reuben Foster is more likely to make the Pro Bowl during his NFL career than new Broncos offensive tackle Garrett Bolles.

Parting shot. Kiz, what do we have to get you a job at Taco Bell where you can be more productive?
