The Facts: The Dolphins had the league's worst offensive line in 2013 and they did the logical thing this offseason; scrap it and start over. They replaced four of the starters from the offensive line in 2013 through the draft class and free agency. That's also a valid area of concern as it isn't realistic to expect five new starters to mesh well as a unit. And the Dolphins will have to start the season without Mike Pouncey and his replacements haven't been doing well.

Do I expect the Dolphins to be better on the offensive line? Probably. Will they struggle some, especially without Pouncey? Yes.

The Dolphins have an unproven stable of running backs with Daniel Thomas and Lamar Miller, and I'm not entirely convinced that Knowshon Moreno can be a functional running back without Peyton Manning. The Dolphins have a significant amount of depth at wide receiver with Mike Wallace, whose production isn't up to the level of his paycheck, Brian Hartline, Rishard Matthews, Brandon Gibson and Jarvis Landry.

Tight end is an area of promise as Charles Clay had a breakout year and the Dolphins drafted Arthur Lynch from Georgia. The Dolphins had a quality pass rush and run defense, but I'm concerned about their secondary outside of Brent Grimes.

Their other corners are Cortland Finnegan, who's starting to be affected by age and injuries, and unproven second year corners Will Davis and Jamar Taylor. The Dolphins need to get more out their draft classes this year as the Dolphins had the third lowest amount of snaps played by rookies in 2013.

Predicted Record: 9-7. Wins against Jets, Patriots, Giants, Redskins, Cowboys, Raiders, Bears, Ravens and Packers
