First of I think Chiefs will beat Chargers in Primetime because I believe they're getting a lot better as a team and unlike some fans I think the draft so far is a success, and because even though last season the chargers did very well, for the first few games they weren't such a great team. Apparently they have a history of not starting out well. Perfect situation for the Chiefs!
Oh and by the way, as the season progresses' the chiefs will probably get better, and the raiders, not so much. The chiefs are playing against the raiders twice in the last 8 games of the season. I'm looking forward to seeing the chiefs beating the faders both games this season!
