The Los Angeles Lakers and Brooklyn Nets are heading home from China, their roles as unwitting participants in a geopolitical drama that neither team had any role in starting or escalating now over. The Nets beat the Lakers 91-77 in Shenzhen, China on Saturday, capping a two-game preseason series in China that was overshadowed by the fallout from a tweet on the protests in the country about Hong Kong by Houston Rockets general manager Daryl Morey. The league has played preseason games in China every year since 2007, with the exception of the lockout-shortened season in 2011.
