1) The Dolphins beat the Steelers;
2) Houston loses at home to New England;
3) the Jets lose at home to Cincinnati;
4) Baltimore loses at Oakland;
5) Jacksonville loses at Cleveland.
That's it. Under that scenario, the Dolphins would finish 8-8 and tied with Pittsburgh, Houston, Baltimore, the Jets and possibly Tennessee.
Division tiebreakers are applied first, so that eliminates the Jets (Dolphins swept them), Pittsburgh (division record) and Houston (division record). Tennessee already has been eliminated because of its 4-8 conference record.
So we're left with Miami and Baltimore, and possibly Denver if it loses at home to Kansas City. Both the Broncos don't matter because they would get in even at 8-8 by virtue of its strength of victory.
That brings us to the Dolphins vs. Baltimore, and the Dolphins would get that tiebreaker, again by virtue of strength of victory.
The bottom line is the Dolphins can only get the No. 6 seed, and if they do make the playoffs, they likely would play at New England.
But that's still a long way away.
