To me the one game I feel most confident about is Baltimore over Pittsburgh.
Pittsburgh just looks like a mess of late and according to metrics like DVOA Baltimore has not only been the best team in the league this year but one of the best in the last 30 some years.
I think that one could be a massacre..... which means Pitt will probably end up winning. Wouldn't bother me, I'd rather not have to face Lamar and Henry in the Super Bowl.
