J.R. Smith can't beat the horn with half-court 3-pointer

The Cleveland Cavaliers headed to the locker room with an eight-point lead at halftime of Game 3 of the NBA Finals, but they easily could have been up by 11.

Guard J.R. Smith knocked down a 3-pointer from the half-court line at Quicken Loans Arena as the buzzer sounded to send fans into a frenzy.

Unfortunately for Cavs supporters, his shot was a split-second too late.
