Vegas has KC as a 10 point dog. They must be convinced Reid rests his starters..
Edit: For anyone who likes percentages. This was taken from a reddit thread.
If we assume each of those results has a 50/50 chance of winning, then chance of getting the 6th seed:
Bal 43.8%
Mia 37.5%
SD 12.5%
Pit 6.3%
But, each of those games is not a 50/50 proposition.
We can use the point spreads to approximate the probability of each outcome:

Baltimore is a 5.5-point underdog, so only has a 32.6% chance of winning. Miami is a 6.5-point favorite, so has a 70.2% chance of winning. Kansas City is a 10-point underdog, so has a 21.1% chance of winning. Pittsburgh is a 7-point favorite, so has a 71.6% chance of winning.
If we take each of those 16 outcomes and multiple the win probability for each, we get these chances of winning the #6 seed:
Miami 65.4%
San Diego 15.8%
Baltimore 15.7%
Pittsburgh 3.0%
----------
If the Dolphins win their game, then the weighted probabilities are:
Miami 93.1%
Baltimore 6.9%
