I hate to be a Friday morning QB that's being pessimistic, but we have to face reality. The Dolphins still hold out hope that they can make it to the playoffs, and you'll hear it from the coach, and some of the players. And, sure, they're mathematically alive. But they're 5-5, have only won once at home, and only of two of their wins were against quality opponents (Green Bay and Tennessee).
In other words, stick a fork in them: they're done.
The division leading Jets and Patriots are 2 1/2 games ahead with 6 left.
And in the wildcard race, they're looking up at the Jets/Patriots, Steelers/Ravens (1 1/2 ahead, each with a head-head win), and Tennessee, Jax, Oakland/KC (1/2 ahead).
Its an insurmountable lead against teams that are flat out better.
They'll have to win 5 out of 6 to even be competitive, and then as coach Shula might have said "we need some help." I just don't see that happening.
