Chris Perkins: Dolphins building physical, versatile roster and the draft is Exhibit A

You hear about the same type of versatility from Louis, who played safety in high school, linebacker in college and could play both in some form with the Dolphins. But at his heart, he’s a linebacker.

“I feel the most at home at linebacker,” Louis said. “I feel the most at home going against tight ends at linebacker, going against running backs at linebacker, beating a lineman at linebacker. And then on passing downs, packages, or heavy run downs, I could definitely play the nickel role when needed.”

The versatility objective even includes players such as tackle-guard Kadyn Proctor, the first-round pick from Alabama, and outside cornerback/slot cornerback Chris Johnson, the first-round pick from San Diego State.

Again, versatility is a huge key for this team.

I covered something similar with the Miami Heat in 2011, when coach Erik Spoelstra, after losing to Dallas in the NBA Finals first year of the Big 3 (Dwyane Wade, LeBron James and Chris Bosh).

Spoelstra traveled out west and talked to then-Oregon football coach Chip Kelly, an offensive innovator, before introducing position-less basketball to the Miami Heat. They won the title in that 2011-12 season, the second year of the Big 3. And they repeated in 2013.

You get the feeling the Dolphins are moving toward position-less football, so to speak.

“The theme,” Sullivan said, “is good football players than can do different things.”

Obviously, there are limits.

For example, the Dolphins claim Proctor can play tackle or guard.

It’s important to note, however, at 6 foot 7, 365 pounds, he’d be one of the biggest guards in NFL history along with the Philadelphia Eagles’ Mekhi Becton (6-7, 363) or Daniel Faalele (6-8, 370) of the New York Giants.

It’s a risk.

But it’s an exciting risk.

“I think what should excite people,” Hafley began, “and what’s exciting to us as coaches as I look at these names, these are not only good football players but they’re smart football players. They’re tough football players.

“It’s going to be cool to see this group mix together because I think they all have a very similar mindset, and I think they all have a little bit of edge to them. That excites me to start coaching them.”

I like the traits the Dolphins are seeking in players. I’m encouraged.

I’ve said this before, but listening to Sullivan and Hafley, I get the feeling that real tackle football is returning to South Florida. Some genuine hardhat-lunch pail, hand-in-the-dirt stuff with foundation anchored in cement, not sand.

I’m wholeheartedly in favor of the ongoing roster construction.

By the way, we know every Dolphins draftee isn’t going to “make it.” Leaguewide, roughly 35 to 40 percent of draftees “make it.”

But I like the fact that the Dolphins are looking for the right types of players — physical, tough, smart and versatile. Good things often follow when teams start going down that road.
