SHENZHEN, China — In July, after buying a blue No. 0 Warriors jersey at the NBA Store in New York City, Ken Wang had a curious request: Could an employee stitch the nickname of his favorite player — Nick "Swaggy P" Young — onto the back? At 5 a.m. Thursday, Wang, a 16-year-old aspiring point guard from Guangzhou, gave up trying to sleep. Seven anxious weeks after a family friend surprised him with tickets to the Warriors' first exhibition game against Minnesota in China, he took a two-hour train ride to Shenzhen to finally see in person the sharpshooter he has long idolized.
