Valencia of the EuroLeague announced the signing of Gonzaga sophomore point guard Mario Saint-Supéry on Saturday, a big blow to the Bulldogs’ hopes of contending nationally next season.The surprise move leaves Mark Few’s team without an established starting point guard as it prepares for its first season in the new Pac-12. The transfer portal is closed.Saint-Supéry leaves behind a talented frontcourt that was supposed to benefit from two European guards but now has neither. Jack Kayil, a 20-year-old who averaged 11.6 points and 3.8 assists last season for Alba Berlin, one of Germany’s top teams, remained in the NBA Draft rather than joining Gonzaga for next season. The Houston Rockets drafted him in the second round and traded him to the New York Knicks.The Athletic’s CJ Moore ranked Gonzaga at No. 12 in his initial early rankings, presuming Saint-Supéry and Kayil would play off each other. Moore dropped the Zags to No. 19 after they lost Kayil, and now there are glaring questions about Gonzaga’s backcourt to offset the return of big man Braden Huff and 7-foot-1 Arizona State transfer center Massamba Diop.Another European addition, 23-year-old Nathan De Sousa (10.9 points, 4.9 assists for Cholet in France last season), will likely move into Saint-Supéry’s starting spot. Houston transfer shooting guard Isiah Harwell, a 2025 McDonald’s All-American who came off the bench as a freshman, will now have more opportunity.
