With a win and Bengals loss at San Diego next week. the Ravens would clinch the AFCN.
Even if they lost all the remaining 4 games after that the best the Steelers or Bengals could do is tie.. and the Ravens already have clinched the best division record.
Looks like New England and Denver could also. Texans haven't played Indy yet so that one is still a bit up in the air.
Bronco/Raven games looms large for a first round bye.
