Chiefs players were happy to see their arch rival, the Raiders, on the losing end of their game today. However, they were able to witness a live game of the emergence of the San Diego Chargers. They know that the Chargers are probably going to show up for the remainder of the season as the 14-2 team they were last year.
This division is not going to be a cake walk for sure. The Chiefs, Broncos, and Chargers are all in it, and the Raiders are not quiet out of it yet. It will be an interesting year, and anyone who wanted to predict the outcome of the afc west, I would call a fool. (unless they predict the Chiefs, then they are wise beyond years.)
There just is no clear cut "better team" at this point.
