I cant remember where I heard this (might have been during the thanksgiving day game), but if the Ravens, Pats and Broncos all finish 13-3, with the Ravens only loss in the last 5 games coming against the Broncos, the patriots finish 2nd. Any other scenario requires 2 ravens losses for either the Pats or Broncos to finish 2nd. The broncos have the toughest route to the 2nd seed because they need a patriots loss, and 2 ravens losses (unless of course the broncos beat the ravens in 3 weeks)
