SANTA CLARA — What do we really know about the 3-0 49ers?
Not all that much, to be honest.
Yes, there are plenty of reasons to be excited about this team — this is the first time they’ve been undefeated at this juncture of the season in 21 years, after all — but some healthy skepticism is justified as well.
This Niners’ offense remains perplexing — is the performance that ransacked the Bengals in Week 2 indicative, or should we expect more of the sputtering we saw in Tampa Bay in Week 1 and on Sunday?
