Miami Dolphins
Strengths
DL: The addition of Suh alongside Wake should provide fits for opposing offenses. Olivier Vernon, who will now be almost certainly seeing single looks, is a competent pass rusher and should flourish at RE. The lone starting holdover at defensive tackle, Earl Mitchell, will also benefit from from the attention garnered by EarthWake & Suhnami ( ). Depth wise, DE Terrence Fede has shown flashes, though his biggest contribution last year was on special teams with a blocked punt vs the Vikings for a safety that sealed the game. Rookie DT Jordan Phillips will also be a player with high hopes as he possesses a massive frame (6'5" 330#) but his knock is his lack of motor.
QB: Ryan Tannehill seems the lost QB at times among his draft class of Luck and Wilson, with possible good reason as he is the lone QB with no post season play under his belt, but Tannehill has significantly improved every year. Tannehill will now be in his 2nd year under OC Lazor, whom helped him last year reach plateaus of 4,000+ yds passing and a 66.4% pass completion rate. Tannehill missed the 30 TD mark (27) but also had some very blatant drops in and around the endzone that would have put him easily at 31 if those catches were made (removes aqua and coral shades). I expect nothing less than more improvement from Tannehill in '15 especially with a revamped receiving corp which brings me to my next strength.
WR: Long gone are Brian Hartline (afraid of YAC and easily tackled by a blade of grass), Mike Wallace (catch radius of a T-Rex and similar sentiment when it came to playing with others and being a teammate), and Brandon Gibson (Wallace's puppet). Enter Kenny Stills, Greg Jennings, 2nd year player, Mr. Velcro Hands aka Jarvis Landry (75% catch rate) and the anti-Wallace, rookie Devante Parker. Greg Jennings will provide veteran leadership, and though that is a cliche' and an overused saying, it will be needed among the young players we have. Stills will replace the speed void left by the departure of Wallace but also brings the ability to run proper routes, adjust to the ball in the air, and make plays above his head. Jarvis Landry will continue to do his thing in the slot and formed an almost immediate chemistry with Tannehill leading the team in catches (84). Devante Parker will begin training camp on PUP due to foot surgery, but is expected back in time for week 1. Parker will provide a red zone threat that the Dolphins have lacked in Tannehill's years with his size, body control, and soft hands, but needs to improve on his route running to offset his just above average speed.
Weaknesses
OL: It's been a significant weakness as the Dolphins have led the league in sacks allowed over the span of the past three years. Last year the acquisition of Brandon Albert at LT and the addition of rookie RT Ju'Wuan James helped this unit but after Albert went down with an injury, James was moved to LT, and the lack of talent at both guard positions quickly hurled the line back into poor pass protection status. Albert looks back on track to play in the season opener but we still have questions with our guard play. I'd be pleased to see the Dolphins take a good look and cough up some more money for G Evan Mathis.
LB: Ellerbe was traded away for to the Saints for WR Kenny Stills (Thanks, Ireland. Never thought I'd utter those words) and Wheeler was cut. Injuries exposed our lack of depth here with the exception of Jelani Jenkins who became our premier playmaker at LB. Koa Misi will return but questions remain as to whether or not he will stay at MLB with a consideration to Kelvin Sheppard and moving Misi back to strongside. Misi gives consistent average play, but has had troubles staying healthy. Biggest weakness here will be at SLB if the said prior moves don't stick. Many unproven players will vie for the spot but it's yet to be seen who will take it as opposed to someone simply landing there out of default. 2nd year player Chris McCain looks to be the favorite
CB: Brent Grimes is savvy veteran but father time is not on his side as his short stature has him rely on his speed and quickness to react. On the other side of the field, your guess is as good as mine. Cortland Finnigan will not be returning and Jamar Taylor is the current front runner as training camp approaches. Brice McCain is the favorite to man the nickel position and Will Allen is recovering from an ACL injury. The Dolphins also acquired Zach Bowman from the Giants and Rookie Bobby McCain (no it's not a McCain family reunion) look to provide depth but overall the unit is very unproven outside of Grimes.
