I'm a Colts fan who happen to live in Florida meaning on the days where I couldn't find a stream or the Colts weren't being nationally broad-casted, I watched a ton of Dolphins game which clearly qualifies me as a potential replacement for current GM Jeff Ireland.
To begin shall I say the obvious, Ryan Tannehill
does not deserve to be a top 8 pick let alone top 30 pick in the first round.
Round 1: DE/OLB Melvin Ingram from South Carolina
The Dolphins may trade down but involving trades in a mock draft is kind of silly nowadays anyways he will play opposite Wake. A dominant pass rush is how you bring great quarterbacks down in the league and with Brady always looking to increase his HOF resume this would be a wise investment. He has played DT, DE, OLB, kick returned 5 times (18 per) freshman year and that means a lot of ways to hurt the Patriots.
Round 2: OG/OT Kelechi Osemele from Iowa State
The Dolphins need a solid RT but most important need to add a playmaker on the right side of the OL and quite frankly Osemele should be able to do both.
Round 3a: CB/FS Trumaine Johnson from Montana
The Dolphins have brought in Johnson and he makes a ton of sense. The lack of Safetys and his potential to play FS or CB could either allow him to hold a CB spot while Smith stays in place or he plays FS. 4 year starter that is big, athletic, and a solid tackler.
Round 3b: TE Orson Charles from Gergia
He doesn't fit a glaring need but is part of a position highly coveted in this passing league .He was arguably a second round type of guy and if not running his 40 yards at the combine didn't drop his status a DUI charge surely should do it. While Clay and Fasano are doing a decent job if Charles falls down, which he will, then this is a pick as every team needs that play-making TE.
Round 4: WR A.J. Jenkins from Illinois
The Dolphins won't have a great WR corp next year but will definitely stock up on 2 things, potential and youth. Unlike Marshall, he has small hands but is reliable to catch a football, agile, and quickness at the line means he's perfect for the WCO. I would expect one of the Dolphins WR to emerge as an okay #1 WR and Jenkins should be at the top of the list.
Round 5: QB Nick Foles
The Dolphins avoided drafting Tannehill as @ #8 he is high risk, medium reward type of player. They should be grabbing a developmental guy in Foles who definitely has accuracy issues and behind both Gerard and Moore, the starter; he should have a retooled arsenal and a better team built around him in case he becomes a shocking franchise QB.
Round 6: SS Duke Ihenacho from San Jose State
Safety needs tons of depth and talent and although he has played a bit of corner Ihenacho is a high reward low risk for the Dolphins at this spot. Another SS that will be drafted late is SS Sean Richardson. He is a strong, physical safety and the combine has proved this lifting up 225 about 20 times.
Round 7: OG/OT Levy Adcock from Oklahoma State
Definitely an interesting target for the later rounds, he has played mostly tackle but has experience in the G posistion and Jake Long could possibly leave next year although confident the Dolphins should be looking for potential guys. He is a great pass blocker yet lacks in his ability to create holes for RB.
