The Dolphins want to be aggressive in free agency in 2020. Well, here’s an aggressive list of players at key positions, like OT, CB and Edge Rusher.

DAVIE — Dolphins general manager Chris Grier was clear in his news conference on Tuesday.

Miami is in the market to spend in free agency, starting in March of 2020.

“We’ve talked about building this long term with sustained success right away,” Grier said. “For us, we’ll be very aggressive. We’re not going to sit here on a bunch of money or anything. The plan is to build a winner here. No one likes losing.”

So spend it is. In all likelihood, the master play does not include spending recklessly, as in paying any defensive tackle $114 million (See: Suh). It’s more about two or three years of layered waves of smart spending.

Miami will be targeting players at need positions, which is, well, pretty much all positions, after a total tear-down of the roster. We believe the positions the Dolphins would be well-served exploring deeply include: right tackle, left tackle, cornerback and edge rusher.

There are other needs. And a few of those positions will be reflected in this list, too. But for purposes of a look-ahead to the 2020 class of free agents, we’ll focus exclusively on the players aged 28 or younger who might make a significant impact at key spots.

It’s always possible Miami elects to sign, say, a 31-year-old right tackle on a two-year deal just as a stop-gap to protecting, lets say, Tua Tagovailoa. And, of course, some of these players may re-sign with their clubs before they hit the market.

According to Spotrac, Miami now leads the NFL with more than $122 million in cap space available in 2020. Other teams with lots of space include the Colts, Raiders, Texans and Bills.

To be clear, Miami should not over-extend themselves. They really need to use their massive credit-card limit intelligently. If any player moves beyond their hard line, simply move on.

Here are 20 players whose agents the Dolphins should keep on speed dial. In a dream scenario, Miami would be able to actually land three players from this list:

1. RT Jack Conklin, 26, Tennessee — Nasty, dominant mauler.

2. LT D.J. Humphries, 26, Arizona — Needs to stay healthy.

3. EDGE Yannick Ngakoue, 25, Jacksonville — Explosive, dynamic rusher.

4. CB Byron Jones, 27, Dallas — Incredible athleticism.

5. DE/DT Chris Jones, 25, Kansas City — Monster. Energetic bully.

6. CB Ronald Darby, 26, Philadelphia — Bouncing back from torn ACL.

7. EDGE Jadeveon Clowney, 27, Seattle — Passed on Miami once.

8. WR Amari Cooper, 26, Dallas — Smooth route-runner from Miami.

9. RT Daryl Williams, 28, Carolina — Strong 2017 followed by knee injury.

10. EDGE Arik Armstead, 26, San Francisco — Sets an edge vs. run.

11. CB Marcus Peters, 27, L.A. Rams — Up and down last year but can great.

12. C J.C. Tretter, 28, Cleveland — Athletic and intelligent.

13. EDGE Dante Fowler, 26, Rams — Former Florida standout, 21 TFLs in 49 games.

14. EDGE Shaq Lawson, 26, Buffalo — Versatile but must stay healthy.

15. S HaHa Clinton-Dix, 27, Chicago — Former Pro Bowler on a “prove-it” deal.

16. S Vonn Bell, 25, New Orleans — Can tackle, cover and rush.

17. EDGE Vic Beasley, 28, Atlanta — Speedy rusher could use a fresh start.

18. RB Jordan Howard, 25, Eagles — Miami was once rumored to be interested.

19. EDGE Bud Dupree, 26, Pittsburgh — See Beasley.

20. CB Artie Burns, 25, Pittsburgh — Miami native could use new squad.
