WWE Hall of Famer ROCKY "SOUL MAN" JOHNSON died yesterday. He was 75 years old. There's no word yet on the cause of death. Johnson wrestled from 1964 to 1991 . . . but his greatest achievement was teaming with TONY "MR. USA" ATLAS to become the first black tag team champions in WWE history. They won the titles in 1983 from THE WILD SAMOANS, who were actually family. Rocky was married to Ata Maivia . . . a member of the family that also includes current superstars ROMAN REIGNS and THE USOS. Another relative you've probably heard of is this guy named DWAYNE "THE ROCK" JOHNSON . . . who just happens to by Rocky and Ata's son. The Rock inducted his dad into the Hall of Fame in 2008.
