Week 15 around the league told us everything and nothing at the same time, as far as NFL power rankings are concerned.
The San Francisco 49ers sure were flat on Sunday against the Atlanta Falcons, eventually losing 29-22 at the last couple of seconds, thanks to a touchdown from wide receiver Julio Jones. And while the Niners loss stinks and hurts a bit in NFL power rankings, it essentially does nothing to San Francisco in terms of the greater playoff picture.
No, Week 17 against the Seattle Seahawks is what matters there.
