The Miami Dolphins have been .500 or worse every year since 2008. If they want to finally snap the five-year mediocrity streak, they will have to hit a home run in the draft.

Unlike last year, when the Dolphins had an embarrassment of riches with 11 selections, the Dolphins have their original seven picks this year and nothing more.

Where the Dolphins had the flexibility to move up to the third overall pick in 2013, they may be more apt to stay put this year or potentially to trade down. This year's draft has been classified as one of the deepest drafts in recent history.

That's good news for a Dolphins team that still has a few holes to fill. They began the rebuilding process on the offensive line, but they are still in need of a second offensive tackle and offensive guard. The Dolphins completely rebuilt their linebacking corps, but they could be in the market for more talent at the position if their recent signings don't pan out.

What positions should the Dolphins be targeting? Which players could be on their radar? Let's take a look at all the pertinent information and some of the possibilities in a draft primer for the Dolphins.
