The Dolphins are a nice story this season exceeding expectations so far with a 6-3 record. But they are not some elite team and find themselves in a tough situational spot.
Miami traveled to Arizona and nipped the Cardinals two weeks ago. The Dolphins beat the Chargers at home last Sunday and now must go on another long flight. This time into high altitude and colder weather.  
The 3-6 Broncos actually give up fewer yards per game and average more yards per game than the Dolphins. The problem for Denver has been a league-high 21 turnovers. 
Protect the ball and the Broncos should win. I'm expecting Drew Lock to play, but if he doesn't I'm fine with backup Brett Rypien, who was the quarterback when Denver beat the Jets, 37-28, on Oct. 1. I understand the Dolphins aren't the Jets. But I'm fine if Rypien plays instead of Lock.
