My mom likes the Steelers, and they are doing pretty well, but I dont think they are well rounded enough to beat the Pats next week. I think that NE's streak may last into the post-season. Id say the Eagles have the best chance of beating them, and then shortly after, the Vikings. I mention Min simply because of the sheer quantity of offense they are producing - whereas NE isnt really well known for blowout scores.
*fingers crossed for the Jets*
