1. The Dolphins looked sloppy
It's only the preseason but this game was meant to be a simulation of the regular season. The mistakes were simple, but they were often and costly.
A drop by Lamar Miller cannot happen in this offense.
Brian Hartline, who normally has one of the most reliable set of hands on the team, was bailed out by a defensive penalty after he dropped a pass on third down.
Matt Moore and Ryan Tannehill each threw ugly interceptions.
