The Miami Dolphins enter a playoff-or-bust year in 2015. This is a very important season for many in the organization, and there are many challenges throughout Miami’s schedule.

With that in mind, I’m ranking the five toughest games on the Dolphins’ schedule. Here is No. 5:

Opponent: vs. Indianapolis Colts

Date: Dec. 27

Analysis: The Week 16 matchup against the Colts could be a very important game. Indianapolis likely will be fighting for playoff positioning in December, and the Dolphins may also be in the same position. The good news for Miami is the team matches up very well against the Colts. Dolphins quarterback Ryan Tannehill is 1-1 against Colts quarterback Andrew Luck and both were close games decided in the fourth quarter. Miami also has the advantage of playing Indianapolis at home. The Dolphins must not fall into the trap of looking ahead to an even bigger matchup against the reigning Super Bowl champion New England Patriots in Week 17.
