George Karl has been a coach for NBA for almost 27 years. He collected 1,175 wins in 1,999 games (58.8%) for six teams he has coached throughout his career. Now that he seems to be retired to coaching, he wrote a book criticizing his former Denver Nuggets players Carmelo Anthony, Kenyon Martin and J.R. Smith.

Karl began coaching the Nuggets in 2004 where Anthony was just a sophomore during that time. Having coached four teams before he took the helm to be a Nuggets coach, many believed that he can guide the young Nuggets team lead by Anthony to greater heights. And the expectation was not denied, for 8 1/2 season he brings the team to playoff appearance every year.

And now, since retiring, he took aim on Carmelo Anthony, Kenyon Martin and J.R. Smith on his upcoming memoir titled "Furious George". According to official NBA website, Karl insults his three former players and describe them one by one. Karl called Melo “a conundrum,’’ a user of people and not a true leader for the Nuggets team during his playing years with the franchise.

He also blasted Melo for being a self-centered player and reluctant to share “the spotlight’’ to his teammates. He also attacks Melo's poor defense during their six years together and mentioned that he could’ve “become the best defender at his position in the NBA’’ but he never did it.

Karl also dragged Martin and Smith alongside Melo and called their trio as "AAU babies" referring them as “the spoiled brats you see in junior golf and junior tennis’’ as per stated in the report. Furthermore, he called Smith's staff as "a posse", a word that got Knicks president Phil Jackson and LeBron James into controversy just recently.

On a separate report by Herald Sun, Martin and Smith fires back on their former coach and took to Twitter their anger. Martin called Karl as an "AWFUL AND COWARD ASS COACH" and pointing that having many wins doesn't make Karl a good coach.

Martin further describes Karl as " selfish, unhappy, missable, cowardly person" and what he wrote to his book is " full of lies and deceit". J.R. Smith made a short comment saying " Still trying to be relevant. Sad just sad."

As of this moment, Carmelo Anthony doesn't release any comment regarding George Karl's book but base on Kenyon Martin and J.R. Smith comment it will surely don't sounds good.
