Objectively, the phins are hard to handicap because many of their draft picks last yr were hurt and contibuted marginally. They have several of last yrs picks (Taylor, Jordan, Thomas) who could make impacts. James, while not a sexy pick, looks to finally stabilize a glaring deficiency on this team for the last several yrs (RT). An improved offensive line alone, makes this a better team as it will make Tannehill and his receivers more efficient and allow Lazor to open up the offense.
Ultimately, it will all come down to Ryan Tannehill's development. If he can become a top 10-15 QB, they will make the playoffs. If he can become a top 5-10 QB, they have a chance at the AFC championship.
