Let's assume for a minute, Chargers/49ers is a 50/50, Ravens/Texans is 75/25 for Ravens, and Chiefs/Steelers is 50/50, all pretty reasonable approximations using point spreads, power ratings and homefield etc. That's means the chances of all 3 Chargers,Ravens and Chiefs winning is 1 in 5 at best. The chances of the three 49ers,Texans and Steelers all winning is about 1 in 16. Some other combination of winners and losers is about 1 in 1.5 or better. So most likely our game will mean something as scenario 3 is far more likely. The team I'm most worried about is San Diego. San Fran has little motivation going in, and if San Diego wins, going into KC and winning is something they have done before.
