Insiders grade Dolphins on offseason moves

The Miami Dolphins made a lot of changes this offseason following a disappointing 8-8 record in 2014. New vice president Mike Tannenbaum was hired in January and brought a fresh set of eyes. He quickly made upgrades, addressed needs and made significant trades and cuts involving veterans such as receiver Mike Wallace and linebackers Phillip Wheeler and Dannell Ellerbe.

So what grade did Miami earn this offseason? ESPN NFL Insider Mike Sando polled several evaluators in Bristol and the collective grade for the Dolphins was a “B.” According to Sando, the addition of Pro Bowl defensive tackle Ndamukong Suh was a home run that raised the bar for the rest of Miami’s offseason moves.

"The best way to attack New England is up the middle and Suh gives them that ability," ESPN’s Bill Polian told Sando. "They really need to run the ball effectively. If they do that and protect [Ryan] Tannehill better, then throw it in fourth gear and let's go."

The Dolphins’ biggest losses were Wallace, who has elite speed at receiver, and former starting tight end Charles Clay, who signed with the Buffalo Bills. Miami replaced them with former New Orleans Saints receiver Kenny Stills and former Cleveland Browns tight end Jordan Cameron. Time will tell if those moves are upgrades.

But overall, this is the deepest and most talented team Dolphins head coach Joe Philbin has had in his four seasons. This is a playoff-caliber roster if Miami stays healthy and the coaching staff gets the most out of its players.
