"F*** George Karl!"
Kenyon Martin made it very clear he still hates his former head coach ... singling him out as the reason the Nuggets missed out on an NBA championship back in the day.
Those Nuggets teams had a bunch of talent in the 2000s ... with Martin, Carmelo Anthony, and J.R. Smith, among other pieces -- long before the days of Nikola Jokic.
However, the talented squad never made it past the first round of the playoffs under Karl's leadership (he coached the Nuggets from 2005 to 2013) ... and Martin -- who played seven seasons in Denver -- blames GK.
"First and foremost, f*** George Karl," Martin said on the newest episode of Gilbert Arenas' podcast. "F*** him and the horse that he rode in on."
"If we had a different coach, we win the championship. [Karl] didn't add no value to nobody! Not one of us. As a coach, as a person, You didn't add value to s*** that we did!"
Martin added, "You're a horrible person George. Live with that, dog. God don't like ugly and you ugly as s*** on the inside."
Kenyon's rant stems from Melo recently revealing on his "7PM in Brooklyn" podcast that Karl called him "overrated" during his time in Denver. Melo is a 10x NBA All-Star, a former scoring champ, a future Hall of Famer ... and the list of accolades goes on.
Karl did not deny Melo's claims ... saying on X Anthony was inexperienced and overrated when he coached him.
It's safe to say it doesn't seem like the beef between Karl and his former players will be squashed anytime soon.
