Here is an official scenario from CBS sports and their playoff scenario breakdowns which are excellent and usually spot on...
PIT has an 18-win advantage in SOV on BAL, and the maximum amount it can change is... by 18 wins. If the difference goes all the way down to zero, then it will go to the next tiebreaker, strength of schedule, which PIT has definitely not clinched yet (the schedules of division opponents only differ in two out of 16 games, and the records of those opponents are similar in PIT/BAL's case).
This means that PIT's advantage in strength of victory only needs to improve by 1 win in order for them to clinch the tiebreaker over BAL. That can happen if a team on PIT's list wins or if a team on BAL's list loses (or both, of course).
There are five games in Week 15 in which this can happen:
-- CIN defeats CLE
-- ATL defeats SEA
-- ARI defeats CAR
-- TEN defeats HOU
-- OAK defeats DEN
Any one of those, plus a Steelers win over the Jets and a Ravens loss against the Saints, and the Steelers clinch the AFC North. So you gotta like the Steelers odds of clinching this division this week if the Saints win their early game with the Ravens which I believe they will, and the Steelers find a way to beat the Jets. And of course just one and only one of the 5 games above that I just mentioned happens which by the looks of it it definitely will.
