Former Denver Nuggets head coach George Karl is set to release a memoir in the near future, and excerpts were released Thursday that did not paint a flattering picture of Carmelo Anthony, J.R. Smith and Kenyon Martin. 

According to the New York Post's Marc Berman, Karl compared his former Nuggets stars to "the spoiled brats you see in junior golf and junior tennis."

Karl also touched on the absence of a father in Anthony's and Martin's lives as a reason for what he perceived as troublesome attitudes. 

"Kenyon and Carmelo carried two big burdens: all that money and no father to show them how to act like a man," he wrote, per Berman. 

Shortly after the excerpts came out, Martin tweeted his thoughts regarding Karl's pointed words on Thursday: 

Martin added: "Everyone that's played for that awful person and coach can't stand the ground he walks on. Having a lot of wins doesn't make you a good coach. He was blessed with great talent. Since we were so bad as players. Tell him to forfeit those Denver wins. George Karl is selfish, unhappy, [miserable], cowardly person. No wonder he's [been] fired every place he has coached."

Furthermore, Martin took aim at Karl after one of the NBA's all-time winningest coaches accused Anthony of focusing his energies on offense and not defense during their time in Denver: 

Martin went into more detail about his reaction to Karl's comments, per Marc J. Spears of the Undefeated on Friday:

We were going to Disney and Al Harrington texted me a little snippet. I hadn’t seen anything until then. I was putting some gas in the truck. I didn’t get a chance to read it all, but just that part alone, I don’t need to read the rest of it. Who are you to talk about that?

Who are you to talk about how I was raised? You know nothing about me. Nothing. I was irate. It took a while for me to calm down. Luckily, I had that drive. It’s a great thing that I had that drive. I calmed down and gathered my thoughts.

According to the New York Daily News' Frank Isola, Anthony told reporters there was "no way" he was going to discuss Karl's book before Thursday's game against the Orlando Magic. 

Before Martin responded, Smith—whom Karl accused of being enabled by his father "to shoot the ball and keep shooting it," per Berman—explained why he believes the 65-year-old wrote about his former players in such harsh terms: 

Reggie Evans, who spent a season-and-a-half with Denver, tweeted: "I had some good Denver Nuggets Teammates. That dude is old and unhappy with himself."

Based on the reaction that's poured out, this may not be the last time former players oppose Karl's accusations with strong criticisms of their own.
