I was messing around with the playoff machine on espn.com a few days ago and there were numerous scenarios were 10 wins still leaves the Dolphins on the outside looking in. In most scenarios however, 10 wins is enough. The loss by Tennessee helps.
If Oakland wins today, the Pats go to Miami next week with the #1 seed still up for grabs. Our game is at 1 and the Raiders play at 4:25 so there's no way the Pats take that game lightly. A loss by Oakland today would not only give the Pats the #1 seed but it would also keep Miami alive for the #5 seed, thus avoiding the Steelers or Ravens in the wild card round. Keep in mind, the Steelers can still get a bye if they win out and Oakland loses out and the Chiefs lose once. Thus, there were also scenarios where the Dolphins play at Kansas City or Oakland in the first round.
I couldn't find a single scenario where the Dolphins got in with 9 wins. Not that that still matters!
The Steelers can get a bye or miss the playoffs altogether. We can get the #5 seed or miss the playoffs altogether.
There is still so much to be determined.
