SportsTicker reports: The president of the Spanish Basketball Federation believes there are many hurdles left to clear before the NBA can put expansion teams in major European cities. NBA commissioner David Stern announced on Saturday that the NBA is continuing to explore plans to expand into Europe and said that such a move could happen within a decade. But Jose Luis Saez, who has presided over a golden era of basketball in his country which culminated in Spain’s gold medal win at the 2006 FIBA World Championship, told PA SportsTicker on Monday that much work needs to be done before the idea can work.
