Nick's take:
The Rams' defense has eight interceptions and 15 sacks already this season. But that's just fine with the Dolphins, who will be more focused on running the ball against a St. Louis unit that allows first downs on 28 percent of its opponents' rushing attempts. Defensively, the Dolphins get the best of former Jets offensive coordinator Brian Schottenheimer's offense.
Prediction: Dolphins 14, Rams 10
Sean's take:
In a battle between two very good defenses, this matchup will boil down to which offense is better equipped to move the ball on the opponent. Miami will force St. Louis to be one-dimensional on offense, while the Rams' aggressive secondary and pass rush will be neutralized by the Dolphins' effective rushing attack. Reggie Bush and Lamar Miller pace Miami to the victory.

Prediction: Dolphins 13, Rams 9
Dan's take:

Prediction: Dolphins 24, Rams 10
Sam's take:
The Dolphins are playing good football, and Ryan Tannehill is the future in Miami. However, the future is not now, and the Dolphins will struggle to stop Sam Bradford, who has been struggling a bit himself as of late. This is how he starts to get back on track: a tough road win against a solid Dolphins squad.
Prediction: Rams 21, Dolphins 20
