Insider's NFL and draft experts -- Todd McShay, Mel Kiper, Chris Sprow and Field Yates -- have teamed up to give a full breakdown of all that should be considered for each team as it enters the 2013 NFL draft. Here we look at the Miami Dolphins.

OT, CB, DE, TE depth

Major need: After losing Jake Long in free agency, the Dolphins need to fill a hole at offensive tackle. They have some flexibility because 2012 second-round pick Jonathan Martin can swing to either side of the line; if the Dolphins add a right tackle, he'd anchor the left side, and vice versa. He needs to improve his strength and pass-set anchor, but Martin has substantial long-term value.

Quiet need: The Dolphins will get more out of Dustin Keller in the passing game than they did Anthony Fasano, but Keller is a far inferior blocker. The Dolphins now lack an above-average blocker at the tight end position, but should be able to find one in the mid-to-late rounds of the draft. Protecting quarterback Ryan Tannehill is essential to this offense taking the next step.

Not a need: Credit GM Jeff Ireland for building the receiving core through free agency, as it has quickly shifted from an area of focus to an area of depth. New additions Mike Wallace and Brandon Gibson should team with Brian Hartline and Davone Bess to give Tannehill a diverse and explosive arsenal of targets. Wallace didn't come cheap, but few players possess his quick-strike scoring ability, something Miami desperately needed.

Depth chart

Jobs in jeopardy: Guard Lance Louis will spend much of his offseason rehabbing from a knee injury that ended his 2012 season while he was with the Bears, but he's a strong contender to start at right guard when he returns, which puts the pressure on incumbent starter John Jerry. While neither was a regular starter in 2012, look for second-year back Lamar Miller to leapfrog Daniel Thomas and open the season as a first-stringer.

Don't mess with it: While the Dolphins have expressed interest in adding a veteran pass-rusher this offseason (John Abraham visited the team), the defensive line is a strength of this team. Cameron Wake is an imposing rusher from the left side, and look for Olivier Vernon to progress as a second-year player in 2013. Jared Odrick has elite run defense traits, and Randy Starks and Paul Soliai are a load to push on the interior.

What free agency solved

The Dolphins completed a two-for-two exchange at linebacker by adding both Dannell Ellerbe and Philip Wheeler in free agency while parting ways with Karlos Dansby and Kevin Burnett. Ellerbe was a hot commodity following a strong postseason, but the overall impact of the new-look linebacking group won't be as dramatic as the addition of three new targets for Tannehill. Tannehill showed extensive promise during his inaugural NFL campaign, but his lack of weapons in the passing game was apparent. Adding Wallace, Gibson and Keller gives Tannehill a sorely needed supporting cast.
