Here are three quick-hit observations from the Raiders’ 31-10 upset over the Chiefs on Sunday.

1. The Chiefs just did themselves a huge disservice.
Coaches and players always say that it doesn’t matter who they play in the playoffs. “We’ll take on anyone – we don’t care,” is what they’ll say. With this loss, the Chiefs will play the Ravens next weekend instead of the Jets (assuming the Colts beat the Titans later this afternoon). Sorry, but that’s a huge difference. The Jets’ pass rush has been non-existent since earlier in the season and Mark Sanchez is playing with a torn shoulder. The Ravens, on the other hand, can get after the quarterback, have the better quarterback and proved last year in Foxboro that they don’t mind playing on the road in the postseason. Get a Chief liquored up enough and I bet they’d tell you they’d rather face the Jets next week rather than Baltimore.

2. Did Charlie Weis already leave for Florida?
That looked like the Kansas City offense from earlier this season. In their final tune up before the playoffs, the Chiefs’ offense was held to 10 points, was limited to 201 total yards (including just 86 through the air) and turned the ball over twice. They had zero rhythm, they couldn’t sustain drives and Matt Cassel was a disaster. It’s not fair to place all the blame on Weis because the players have to execute, but it makes you wonder if his head isn’t already in Gainesville after accepting Florida’s offer to become its next offensive coordinator.

3. Tom Cable should retain his job.
ESPN’s Adam Schefter reports that Cable is unlikely to return as head coach of the Raiders in 2011. Why? Oakland finished 8-8 and went undefeated (6-0) in division play this year. Despite having scattered talent, Cable didn’t have a lot to work with and Al Davis’ prized offseason acquisition, Jason Campbell, was highly inconsistent. Yet, they were in the playoff hunt into the final two weeks of the season. Maybe Davis will promote offensive coordinator Hue Jackson after the Raiders’ offense blossomed throughout the course of the year, but would Jackson provide an upgrade? For once, Davis should stay the course and provide his team with some stability at the head coach position.
