LeBron James doesn't agree with NFL teams that won't employ Colin Kaepernick. Add Cleveland Cavaliers superstar LeBron James to the NBA contingent which believes former San Francisco 49ers quarterback Colin Kaepernick is being blackballed by the NFL for his social views. Golden State Warriors coach Steve Kerr and star Stephen Curry, having followed Kaepernick's career closely in the Bay Area, both consider it no coincidence that a QB who nearly led the Niners to a Super Bowl victory is out of the league at age 30 after his decision to kneel in protest of racial inequality and social injustice during the national anthem fueled a debate that found its way to the White House.
