Two days later, there is still no clarity on what J.R. Smith knew when he grabbed that offensive rebound in the final seconds of regulation of Game 1 of the NBA Finals. "I can't say I was sure of anything at that point," Smith said. All he and the Cleveland Cavaliers are sure of now is this: They're down 1-0 to the Golden State Warriors in the NBA Finals, with Game 2 on Sunday night and Smith knowing that he's going to be booed, made fun of, mocked and probably worse by the crowd at Oracle Arena.
