After finishing second to the Patriots in the AFC East for back-to-back seasons and missing the playoffs for a fifth straight year, the Dolphins made some big moves last offseason to try to make a playoff push.

Offensive coordinator Mike Sherman was shown the door after only two seasons, and in his place, the Dolphins brought in Bill Lazor to run the offense. They made one of the biggest free agent signings of the offseason, bringing in former Chiefs tackle Branden Albert to anchor their offensive line that gave up the most sacks in the league in 2013. They also brought in rumors of a big contract extension for him.

Landry developing alongside Tannehill will go a long way to getting the passing game going, but if Mike Wallace does indeed leave for greener pastures, Miami will likely need to bring in another weapon, with the alternative being Brian Hartline lining up as their number-two receiver.

While Juwan James was kind of a mess this year, he was also a rookie being asked to start 16 games. If he can develop and Branden Albert can stay healthy, the Dolphins offense should be that much more effective.

On defense, Miami needs to stop taking strides backwards to stop holding the team back. If 2015 sees the defense once again hold the Dolphins back, and maybe even out of playoff contention, defensive coordinator Kevin Coyle may find himself on the way out.

With Buffalo showing signs of improvement and New England a perennial powerhouse, the playoffs won't come easily for Miami in 2015. But with a strong offseason there's no reason to believe they can't make a strong push for it.
