Eclipse Sport Management is a boutique international hockey agency with a New York NHL contract base and a wide European agent network. The agency traces back to the mid-1990s, when Michael Deutsch and Scott Greenspun built the Eclipse/Impact Sports Management platform around NHL and international player representation. Deutsch’s profile is unusual for a hockey agent because he is also a New York and New Jersey attorney with litigation, securities and arbitration experience. That legal background fits Eclipse’s long-running work in multi-million-dollar contracts, salary arbitration and cross-border player negotiations.
Eclipse’s current public NHL book is led by Martin Nečas, William Karlsson, Lukáš Dostál and Pontus Holmberg. Nečas’ eight-year, $92M Colorado extension gives the agency a major future contract milestone, while Karlsson’s long-term Vegas deal remains the largest active contract in Eclipse’s current cap book. The agency also has a strong Czech lane through Nečas, Dostál, Michal Postava, Eduard Šalé, Michal Kunc and Jakub Brabenec. Its Swedish side remains visible through Karlsson, Pontus Holmberg, Anton Rödin, Victor Ejdsell, Viktor Lööv, Anton Mylläri and Henrik Eriksson.
Eclipse has also had important historical ties to elite European NHL talent, including former representation connected to Elias Pettersson and Nikita Kucherov. The current profile is smaller than the mega-agencies but more international than a typical boutique. Its value is strongest in NHL-Europe transitions, salary arbitration knowledge, Czech/Swedish recruitment, and veteran European placement. Eclipse is best described as a compact, legally sophisticated agency with a meaningful NHL contract book and deep European player relationships.
