Link to a bigger screen of that here. I am bored while tutoring today and I made a breakdown of the head-to-head with the AFC West. For those of you who do better with graphs instead of charts, you can see the breakdown here instead. Oakland has a better overall win-percentage (barely) because they completely dominate the Broncos and Chargers, but with positive margins of wins over the other teams, it's clear the Chiefs own the West. We do need to pick it up with the wins against the Chargers: they could possibly tie the series up next season (don't worry; they won't). (All statistics stolen shamelessly from PFR)
