Doug Farrar: Miami Dolphins
Dolphins quarterback Ryan Tannehill was sacked 58 times last season, the most in the NFL by 10 over Baltimore's Joe Flacco. That had something to do with the Richie Incognito/Jonathan Martin bullying incidents, but neither Incognito nor Martin were pass-protectors at even a league-average level. Getting Branden Albert to fill Martin's old shoes at left tackle and selecting right tackle Ja’Wuan James in the first round of the 2014 draft should do a lot to keep Tannehill upright. And if Tannehill is given time to make things happen, he'll do it -- though his results will be inconsistent at times.
This preseason, James has given up no sacks or pressures of any kind. That doesn't tell the whole story, but it does indicate that James is a mammoth upgrade over Tyson Clabo, who was a swinging gate at right tackle last season. Head coach Joe Philbin is still evaluating the running back tandem of Knowshon Moreno and Lamar Miller, but the line will help. And maybe with some time in the pocket, Tannehill can get some of those deep balls out to speed receiver Mike Wallace, who caught just six passes in which the ball was thrown over 20 yards on 36 such attempts in 2013.
On defense, the Dolphins have a good front line and pass rush (which could be great if they finally figure out how to use Dion Jordan), a pretty good secondary, and linebackers who need to step up. Also on the list of individuals who need to step up is Philbin, whose demeanor alternated between "fake tough guy" and "totally clueless" when things fell apart for the team last season. I'm not convinced that Philbin is made to be a head coach -- he seems more the assistant type -- but there's a better front office in Miami these days, and the improved talent should be enough to buy the Dolphins a playoff spot in an AFC East that appears to be pretty mediocre outside of the Patriots.
