[...] Williams learned during a routine checkup in New York that he required arthroscopic surgery on his right knee. The Warriors held an informal open practice Wednesday night at Oracle Arena, which featured the rookies' annual talent show. The highlight? A record crowd of 13,500 was treated to guard Patrick McCaw's rendition of Soul for Real's "Candy Rain."
