Jonas Valanciunas’ surprise move may shake up free agency—potentially clearing the way for a major Nuggets offseason splash.

Jonas Valanciunas has been lured into considering a return to the EuroLeague, where the Greek club Panathinaikos has offered him a three-year contract worth $13 million, according to a report by BasketNews. One problem: Valanciunas is under contract in the NBA. For $10.4 million next season, to be exact.

His imminent decision to ditch the U.S. for Europe puts a damper on Denver's excellent roster-building run this summer, as the Nuggets look to retool their roster around three-time MVP starting center Nikola Jokic, power forward Aaron Gordon, and guards Jamal Murray and Christian Braun.
