5. Colbert "Black Just" Johnson
Nas: "Rest is peace to Black Just/Riding through Jamaica, Queens in his black truck" ("A Queens Story")
50: "In a conversation over shrimp and lobster at Benihana's/Heard Chico stopped boxing, and started robbing diners"
While 50 may not mention Johnson by name, the implication is impossible to miss. He ran a popular boxing program in Queens that was financed by the powerful Supreme Team drug gang. While Black Just may have been held in high esteem by both rappers -- 50 has reminisced fondly about how "Blackie was that nigga to me" -- it wasn't enough to stop him from being murdered in 1999.
