Well, look, I always say you dont' even know who a team is until after week 4, so let's not start writing Conf Championships yet. Nevertheless, Niners look good, but the Vikings are unbeaten too.
SF has for a number of years in a row now seemed to be a legitimate contender for another ring, if only they could keep their players on the field. Deebo is now a hammy, which means they have to lean more into C-Mac, Kittle (who are both very injury prone), and the Ghost of Mike Evans.
They look great, but they usually feel like a countdown to the ER for me. If they can manage a killer trade (the Marvin Harrison deal would have been perfect for them) for some more YOUNG offensive talent, I would believe more.
