MLS Free Agency 2025: One Player Every Club Should Be Watching Closely

With the 2025 MLS Free Agency list officially released, front offices around the league are already mapping out their offseason priorities. While depth pieces and short-term fixes will always draw interest, it’s the true difference-makers — the players capable of altering a team’s trajectory — who deserve the most attention.

Among this year’s class, one name stands out as a potential franchise-level addition: Justin Haak.

At just 24 years old, Haak belongs in a rare category of free agents — players who aren’t merely stopgaps, but long-term solutions capable of anchoring elite teams. These are the signings that can redefine a roster, and in this free-agent class, Haak sits near the very top of that tier.

A Modern Defender Built for MLS

Haak’s profile is unusually versatile for a player his age. Developed as a homegrown defensive midfielder, he has successfully transitioned into a full-time center back at the MLS level — without sacrificing the technical comfort that defined his early years.

Physically, Haak has the frame to compete with league forwards and hold his ground in the penalty area. He may not dominate the air, but he consistently wins his duels and positions himself intelligently. What truly separates him, however, is his ability with the ball at his feet.

Where many MLS center backs play safe, Haak plays progressive.

The Build-Out Advantage

New York City FC were at their best this season when Haak operated as the connective tissue between defense and midfield. He routinely drew the first line of pressure before slicing through it with precise passes, turning defensive possessions into attacking opportunities in seconds.

That skill set is gold in MLS — particularly for teams that prioritize controlled build-ups rather than direct play. Even more impressively, Haak continued to slide back into defensive midfield when injuries or tactical needs required it, maintaining a high level of performance throughout the season.

How many center backs in MLS can seamlessly switch roles and still perform at a conference finalist standard? The list is very short.

A Free-Agent Head-Scratcher

Perhaps the most surprising aspect of Haak’s availability is that he reached free agency at all. Players with his age profile, positional flexibility, and upside are typically locked down early — especially by clubs that value continuity and development.

Instead, Haak now enters the open market at a moment when he’s poised to peak. Any team seeking a long-term answer in central defense — or a hybrid defender capable of reshaping build-out play — should be circling his name in bold.

In a league where roster efficiency matters as much as star power, Justin Haak may be the most valuable free agent MLS has to offer in 2025.
