High school career
Felton began his basketball career at Latta High School in Latta, South Carolina. There he led his high school to two state championships and a career record of 104–9. In the process, he set state scoring records with 2,992 points and 117 3 pointers.
Felton won the South Carolina Mr. Basketball award as both a junior and senior, and was named Naismith Prep Player of the Year in 2002. He was MVP of the 2002 Roundball Classic at the United Center in Chicago, and was selected for the 2002 McDonald's All-American Game (at Madison Square Garden in New York City). Felton played in the McDonald's All-American game on the same team with two future New York Knicks teammates, Carmelo Anthony and Amar'e Stoudemire.
In his freshman year, he was voted Carolina Player of the Year and ACC Freshman of the Week three times. He had 236 assists, and averaged 12.0 points a game. During his sophomore year, he was a finalist for the Bob Cousy Award and the Naismith College Player of the Year Award, had 213 assists, and led the Tar Heels in steals (63) and free throw percentage (81%) while averaging 11.5 points per game. Also notable in his second year, Felton set a school-record single-game 18 assists against George Mason on Dec. 7, 2003.
In his third and final season at North Carolina, Felton led the Tar Heels along with fellow juniors Rashad McCants and Sean May and freshman Marvin Williams to the 2005 National Championship over the University of Illinois Fighting Illini on April 4, 2005 in St. Louis. This was the fourth men's basketball championship in UNC's history ( 1957, 1982, 1993, 2005). Felton hit a key three-pointer over Deron Williams to break a 65–65 tie late in the game, and then came up with a crucial steal in the final seconds when Illinois had a chance to either tie the game or take the lead. His two free throws after the steal provided the final scoring in the game.
Felton averaged 12.9 points and 6.9 assists per game during his junior season and showed a much-improved shooting touch. In recognition of his efforts, he was voted to the All-ACC First Team that season. Felton also won the Bob Cousy Award that honors the best collegiate point guard. Due to his excellent junior campaign EA Sports awarded Felton the cover of NCAA March Madness 06.
2005–2010: Charlotte Bobcats
Felton was selected 5th overall in the 2005 NBA Draft by the Charlotte Bobcats. Felton was drafted after point guards Chris Paul and Deron Williams. University of North Carolina teammates Marvin Williams, Rashad McCants and Sean May were also selected in the draft. Felton showed promise right out of college, having his breakout game scoring 31 points against the Phoenix Suns in a Bobcats loss. Felton's best all-around game of his rookie year occurred January 28, 2006, when he recorded 18 points and 13 assists against the Washington Wizards. Felton started 54 of 82 games for the Bobcats and averaged 11.9 points per game, 5.6 assists per game, and 3.3 rebounds per game. In his rookie year, Felton recorded 13 double-doubles. Felton was selected to the NBA All-Rookie Second Team. Felton came into his second year as the Bobcats' starting point guard. Felton improved in mostly every statistic category, raising his assist per game tally from 5.6 to 7.0. Instrumental in the increase was the improved play of teammates Gerald Wallace, Sean May, and Emeka Okafor and the addition of then-rookies Adam Morrison and Walter Herrmann. Despite Felton's solid season, the Bobcats missed the playoffs. Coming into his third year, the Bobcats looked for more talent for Felton to distribute to, bringing in popular scoring shooting guard Jason Richardson. The 2007–08 season was still, however, a season of rebuilding for the Bobcats; several players took a step back instead of a step forward. May, Morrison and Herrmann took steps back and the Bobcats were plagued with injuries. The Bobcats once again missed the playoffs. Felton improved on his sophomore campaign, putting up 14.4 points per game, 7.4 assists and 3.0 rebounds per game. Felton also became more efficient, raising his shooting percentage from 38% to 41%. Felton still, however, struggled shooting from three-point range, one of his biggest deficiencies coming out of college. In his fourth season in the NBA, the Bobcats had big expectations for Felton and expected him to take a big leap. The Bobcats even put more pressure on Felton by drafting DJ Augustin in the 2008 draft. The Bobcats hired coach Larry Brown to be their head coach. However Felton regressed in scoring, assists and FG%. The Bobcats dealt Richardson and began to rebuild once again. The Bobcats missed the playoffs and hadn't made the playoffs since being created in 2004. During the 2009 off-season, Felton was a restricted free agent. However, he did not sign a contract offer with another team and returned to Charlotte for one more season after signing the qualifying offer on September 23, 2009. During the 2009 season, the Bobcats had their most successful year. However, Felton did not; he saw his assist and scoring numbers drop to their lowest point since his rookie season. Felton however raised his FG% to a career-high 46% and improved his stroke from the three-point line, shooting 38.5%. In March, Michael Jordan became the majority owner of the Bobcats. The Bobcats added Stephen Jackson and Tyson Chandler via trades, and Tyrus Thomas and Larry Hughes late in the season. The Bobcats made the playoffs for the first time in franchise history. In the playoffs, Felton averaged 11.8 points per game, 2.5 rebounds per game and 5 assists per game. The Bobcats were swept out of the playoffs, and Felton became a free agent at the end of the season.
2010–2011: New York Knicks and the Denver Nuggets
On July 9, 2010, Felton agreed to a contract with the New York Knicks. On July 11, 2010, the deal was finalized for two years and $15.8 million. Felton was selected as co-captain for the 2011 season alongside fellow free agent signee Amar'e Stoudemire. Early in the year, Felton had trouble working the pick-and-roll with Stoudemire. But after a few games, Felton gained confidence and in no time was a fan-favorite in New York. Felton hit a number of clutch shots, including a step-back fade-away three-pointer that pinballed into the net against the Toronto Raptors. The change of scenery seemed to be helping Felton; his play also saw the Knicks in playoff contention for the first time since 2004. Felton's time in New York, however, would not last long. On February 22, 2011, Felton was traded to the Denver Nuggets in a three-way deal which also involved the Minnesota Timberwolves that brought Carmelo Anthony to New York. The deal sent Felton along with teammates Wilson Chandler, Danilo Gallinari, and Timofey Mozgov to the Denver Nuggets. With the Knicks, Felton was on pace to have his best season ever. Felton also registered a fair number of All-Star votes by fans. Felton averaged 17.1 points, 9.0 assists, 3.6 rebounds, and 1.8 steals per game in 38.4 minutes a game. In Denver, Felton was utilized mostly off the bench behind fellow University of North Carolina guard Ty Lawson. Felton and the Nuggets made it to the playoffs where the Nuggets went up against Kevin Durant, Russell Westbrook and the Oklahoma City Thunder. Felton averaged 11.6 points, 6.5 assists and 1.8 rebounds in the postseason. As a whole, 2010–11 was Felton's best season; he averaged 15.5 points per game and 8.6 assists per game.
Raymond, however, expressed dissatisfaction of playing off the bench and behind Lawson. On June 23, 2011, during the 2011 NBA Draft, Felton was traded to the Portland Trail Blazers for veteran point guard Andre Miller and the #26 overall selection in the draft, Jordan Hamilton from the University of Texas. In the deal, the Trail Blazers also dealt Rudy Fernande and the rights to Finnish guard Petteri Koponen.
2012–present: Return to New York Knicks
On July 16, 2012, Felton and Kurt Thomas were traded to the New York Knicks for Jared Jeffries, Dan Gadzuric, the rights to Kostas Papanikolaou and Giorgos Printezis, and a second round draft pick. Felton signed a 3 year, $10 million dollar extension with the Knicks. Felton went under fire because of the shape he was in with Portland. Felton acknowledged his weight, saying, "I won’t make any excuses, I wasn't in shape." At a Las Vegas Summer League game between the Knicks and the Toronto Raptors, Felton told Walt Frazier and Mike Breen he had lost more than 20 lbs. Felton also said he felt he was better than Jeremy Lin, who was signed by the Houston Rockets that offseason. On November 2, 2012, when the season tipped off for the Knicks, Felton recorded 14 points and 9 assists in a 104-84 win over the defending champion Miami Heat. On November 15, 2012, Felton led the Knicks to a 104-100 road victory over the San Antonio Spurs as he helped his team overcome a 12 point deficit in the fourth quarter with his 25 points and 7 assists. On December 6, 2012, Felton scored a season-high 27 points in a 112–92 road win over the Heat to hand them their first home loss of the season. The Knicks won the game without Carmelo Anthony. In mid December, Felton reportedly suffered a hand injury, but decided to play through it for some games. After consulting a hand specialist, and being informed he didn't have to have surgery, it was noted he would miss 4-6 weeks. On January 23, 2013, he was medically cleared for contact, and he made his return on January 26, 2013 against the Philadelphia 76ers
