Kenyon Martin

As a rookie for the New Jersey Nets, Martin averaged 12 points, 7.4 rebounds and 1.7 blocks per game. He was named to the NBA All-Rookie First Team and finished second in voting for NBA Rookie of the Year. In his second season, Martin averaged 14.9 points, 5.3 rebounds, 1.3 steals and 1.7 blocks per game in helping the Nets rise from last place in the Atlantic Division to an Eastern Conference title and the best season to date in the Nets' NBA history. Along with Jason Kidd, Kerry Kittles, Keith Van Horn and Richard Jefferson, Martin led the Nets to the 2002 NBA Finals, where they were swept by the Los Angeles Lakers. In his third season Martin again helped his team into the NBA finals, where the Nets lost in six games to the San Antonio Spurs. The next year, Martin averaged 16.7 points, 9.5 rebounds and 1.3 blocks en route to his first NBA All-Star selection, as a backup forward for the Eastern Conference All-Stars. In the 2004 NBA All-Star Game, Martin scored 17 points, grabbed 7 rebounds and had 3 assists.

Martin and teammate Alonzo Mourning almost fought when Martin mocked Mourning's life-threatening kidney disease.[4] Martin later admitted that he had made a mistake and apologized to Mourning. On an episode of the Scoop B Radio Podcast, Martin told Brandon Scoop B Robinson that Mourning thought that Martin should have been working as hard as he was in morning shootarounds, but he was never a shootaround guy.[5] Martin now participates in Mourning's annual charity basketball game (see below "Off the court").

At the end of the 2003–04 season, Martin was traded to the Denver Nuggets for three future first-round draft picks in a sign-and-trade deal.

Martin played in 70 games during the 2004–05 season, averaging 15.5 points and 7.3 rebounds; however, a problem with his knee was detected shortly into the off-season, and on May 16, 2005, Kenyon underwent microfracture surgery on his left knee.

During the 2005–06 season, Martin missed 26 games due to knee tendinitis, but was able to return in time for the playoffs. During that playoff series against the Los Angeles Clippers, Martin was suspended from the Denver Nuggets indefinitely for "conduct detrimental to the team."[6] During halftime of game two of the first round series, Martin got into an argument with head coach George Karl over his playing time, and refused to play for the second half of the game. During the offseason, Karl and Martin apparently "patched things up."[7]

Believing injuries were behind him, Martin learned the swelling now occurring in his right knee would require another microfracture procedure. On November 15, 2006, after playing two regular season games, Martin underwent his second knee operation in less than two years.[8] Martin is believed to be the first NBA player to have, and to return from, microfracture surgery on both knees.[9]

Martin was fined $15,000 by the NBA when, during the third quarter of a 2006 game against the Chicago Bulls, Martin as well as some of his friends got into a verbal altercation with some fans. He was also cautioned to no longer bring his entourage to games.[10][11]

To symbolize a fresh start to his career, Kenyon changed his uniform number from 6 to the number 4, which he wore in college, for the 2007–08 season.[12]

Martin became an unrestricted free agent in the summer of 2011; however, due to the 2011 NBA lockout, he opted to sign a one-year contract with the Xinjiang Flying Tigers of the Chinese Basketball Association. His contract reportedly would have made him the highest paid player in the Chinese league's history.[13][14] On December 24, 2011, Martin was released from the club so that he could "take care of family affairs".[15] Martin was initially not allowed to return to the NBA until the Flying Tigers' season ended on February 15, 2012, if not later due to the 2012 CBA Playoffs. However, the FIBA granted him an earlier release on February 2.[16]

On February 3, 2012, Martin signed with the Los Angeles Clippers.[17] In his first game with the Clippers, Martin scored 6 points and collected four rebounds in a loss to the Cleveland Cavaliers.

On February 21, 2013, Martin agreed to join the New York Knicks on a 10-day contract, which reunited him with Jason Kidd.[18] He officially joined the team on February 23.[19] He was signed to a second 10-day contract on March 5,[20] and signed for the remainder of the season on March 15.[21] Upon his signing, he provided a large amount of help to a Knicks team that was depleted in the frontcourt, replacing Tyson Chandler, who was out with a neck injury, in the Knicks' starting lineup. On July 25, 2013, Martin re-signed with the Knicks for the 2013–14 season.[22]

On January 9, 2015, Martin signed a 10-day contract with the Milwaukee Bucks.[23] He went on to sign a second 10-day contract on January 19,[24] and a rest-of-season contract on January 29.[25] On February 19, 2015, he was waived by the Bucks.[26]

On July 3, 2015, Martin announced his retirement from professional basketball.[27]
