Berg's appointment comes at a critical juncture for MLS, as the league seeks to capitalize on the growing popularity of soccer in the U.S. following the 2026 FIFA World Cup. The transition to a European-style calendar and the negotiation of a new media rights deal will be key tests of his leadership. Additionally, Berg will need to address the league's ongoing efforts to attract and retain fans, particularly in the post-World Cup and post-Lionel Messi era.
