Hip-hop legend Kurtis Blow strongly believes NFL owners are conspiring to keep Colin Kaepernick out of the league -- to send a message to other players to stay quiet about off-the-field issues.
Blow was at the United We Stand rally in front of NFL headquarters in NYC -- when he explained why Colin should be hailed as a hero, not a villain.
He's dead serious about his conspiracy theory -- and calls one team in particular to buck the trend and hire #7 before the season starts.
