All four AFC West teams have played Week 4 and the Kansas City Chiefs are now officially on the board in the AFC West standings. The Chiefs victory over the Minnesota Vikings gave them their first victory of the season. Both the Chiefs and San Diego Chargers won on Sunday while the Oakland Raiders and Denver Broncos lost.

Here's how the AFC West standings shake out after one month:

1. San Diego Chargers (3-1): San Diego has few problems with the Miami Dolphins in a 26-16 victory. They move to 3-1 and control the AFC West in first place. They'll have a winnable game next week against the Broncos before going on a tough three-game stretch: at New York Jets, at Chiefs and hosting the Green Bay Packers. If the Chiefs can just get some momentum....

2. Oakland Raiders (2-2): Oakland moves to second place after dropping a double digit loss to the New England Patriots. You just never what you're going to get with the Raiders (except for the penalties, those are always there). The Chiefs play the Raiders in three weeks so we'll keep an eye on them. Oakland travels for a tough game in Houston before hosting the Cleveland Browns and Chiefs.

3. Kansas City Chiefs (1-3): KC moves to 1-3 on the season with their first W of the 2011 season against the Vikings. Last Sunday looked a little more like the 2010 season, if only the Chiefs can keep this up. The Chiefs will travel to Indy before the bye and then they'll go on the road against Oakland before returning to Arrowhead on Halloween night to host the Chargers.

4. Denver Broncos (1-3): Same as the Chiefs. They were thoroughly dominated by the Packers, as expected. They have a couple of tough games ahead -- hosting San Diego, traveling to Miami and then hosting the Lions.
