At least one former NBA player was unimpressed by D'Angelo Russell's recent endorsement of new Los Angeles Lakers coach Luke Walton.
After learning Russell said he's "always been a fan" of Walton, Jackson took to Instagram to call out the 20-year-old for "brown nosing."
It's not the first time Jackson has publicly shamed the Lakers point guard, as he also had a special message for the youngster last season.
