The Dolphins were expected to contend for the division crown behind a talented rookie class that was supposed to add some sizzle to the lineup. However, Joe Philbin didn't appear to have a solid plan for assimilating the first-year group into the lineup -- and their negligible contributions played a role in his dismissal. DeVante Parker finished the season with 26 receptions and three touchdowns, but didn't make the impact that most anticipated from the team's top pick. Although he closed the season strong (22 of his 26 reception came in Miami's last six games), Parker should've played a much bigger role for the Dolphins as a rookie. Jay Ajayi, who missed time with a chest injury, showed flashes of talent and potential in minimal action. He could take on a bigger role under a new regime as a big back with a physical running style (especially if Lamar Miller leaves in free agency). Jordan Phillips is an impressive talent with a wide array of skills, but he needs more seasoning to become a steady contributor in the NFL. Tony Lippett and Bobby McCain are untapped commodities as perky cornerbacks with intriguing instincts and athleticism. Lastly, the Dolphins received solid contributions in the kicking game from undrafted free agents Matt Darr (punter) and Andrew Franks (placekicker). It's uncommon for a pair of rookies to man significant roles on special teams, but Miami's young duo played well in Year 1. Grade: C
