Roy Tarpley shows why he's the 1987-88 NBA Sixth Man of the Year by coming off the bench and energizing the Dallas Mavericks team and crowd (notice how the crowd reacts to him coming in the game). Nice double double by Roy - 16 points and 14 rebounds. This is Tarpley's last full season without injuries or off court problems. Cocaine's helluva drug. February 12, 1988.
