Newly hired offensive coordinator Bill Lazor takes over an offense that finished 27th in total yards per game, 26th in rushing yards per game, and 26th in points per contest. Lazor, who helped Nick Foles develop into the NFL's top rated passer as the Eagles' quarterback coach last season, must find a way to speed up Ryan Tannehill's development, turning the Dolphins' 2012 first-round pick into one of the NFL's top 15 quarterbacks in his third season as a starter.
The breakdown: This is Lazor's first opportunity as an NFL offensive coordinator, so he's got plenty to prove. He'll need to incorporate some of the fast-paced approach he learned from Chip Kelly in Philadelphia in order to get the Dolphins' stagnant offense in gear.
