Answer by taking a quote from the following article:

Kareem Abdul-Jabbar (born Ferdinand Lewis Alcindor Jr.; April 16, 1947) is an American retired professional basketball player who played 20 seasons in the National Basketball Association (NBA) for the Milwaukee Bucks and the Los Angeles Lakers. During his career as a center, Abdul-Jabbar was a record six-time NBA Most Valuable Player (MVP), a record 19-time NBA All-Star, a 15-time All-NBA selection, and an 11-time NBA All-Defensive Team member. A member of six NBA championship teams as a player and two as an assistant coach, Abdul-Jabbar twice was voted NBA Finals MVP. In 1996, he was honored as one of the 50 Greatest Players in NBA History.

Since 2005, Abdul-Jabbar has served as a special assistant coach for the Lakers. He had been interested in coaching since his retirement, and given the influence that he exerted on the league during his playing days, he thought that the opportunity would present itself. However, during his playing years, Abdul-Jabbar had developed a reputation for being introverted and sullen. He did not speak to the press, which led to the impression that he disliked journalists. In his biography My Life, Magic Johnson recalls instances when Abdul-Jabbar brushed him off when Magic (as a ball boy) asked for his autograph, Abdul-Jabbar froze out reporters who gave him a too-enthusiastic handshake or even hugged him, and he refused to stop reading the newspaper while giving an interview. Many basketball observers, in addition to Abdul-Jabbar, believe that Kareem's reticence, whether through disdain for the press corps or simply because of introversion, contributed to the dearth of coaching opportunities offered to Abdul-Jabbar by the NBA. In his words, he said he had a mindset he could not overcome, and proceeded through his career oblivious to the effect his reticence may have had on his future coaching prospects. Abdul-Jabbar said: "I didn't understand that I also had affected people that way and that's what it was all about. I always saw it like they were trying to pry. I was way too suspicious and I paid a price for it." Since he began lobbying for a coaching position in 1995, he has managed to obtain only low-level assistant and scouting jobs in the NBA, and a head coaching position only in a minor professional league. Abdul-Jabbar has worked as an assistant for the Los Angeles Clippers and the Seattle SuperSonics, helping mentor, among others, their young centers, Michael Olowokandi and Jerome James. Abdul-Jabbar was the head coach of the Oklahoma Storm of the United States Basketball League in 2002, leading the team to the league's championship that season, but he failed to land the head coaching position at Columbia University a year later. He then worked as a scout for the New York Knicks. Finally, on September 2, 2005, he returned to the Lakers as a special assistant to Phil Jackson to help the Lakers' centers, and in particular their young draftee Andrew Bynum. Abdul-Jabbar's influence has been credited with Bynum's emergence as a more talented NBA center. Abdul-Jabbar also served as a volunteer coach at Alchesay High School on the Fort Apache Indian Reservation in Whiteriver, Arizona in 1998. In 2016, he performed a tribute to friend Muhammad Ali along with Chance the Rapper. He is also co-author of a comic book published by Titan Comics entitled Mycroft Holmes and the Apocalypse Handbook. CANNOTANSWER
