Toronto Raptors

Drafted in the first round by the Raptors in 2000, Peterson was a fan favorite from the moment he stepped on the floor. While enjoying some early success in his professional career, Peterson's production faced a steady decline, before stepping up in the wake of the new era of Raptor youngsters being ushered in, taking on a more expansive leadership role and transforming himself into an elite perimeter defender, a clutch performer and consistent scorer. He is known for his three-point shooting, acrobatic shots, defense, and fearless driving to the basket.

On December 28, 2005, Peterson set a record for career games played as a Raptor, surpassing Alvin Williams with 418 games played. Peterson also leads the NBA in longest consecutive games played, appearing in 371 straight until November 22, 2006, when he missed his first game in over four years.

Peterson posted career highs in points and rebounds averaging 16.8 points and 4.6 rebounds and threw in 2.3 assists per game through 82 games played in the 2005–06 season.

Perhaps the biggest highlight of his career occurred against the Washington Wizards on March 30, 2007 in a game that helped determine the two teams' playoff seeding. The Raptors trailed 109–106 with only 3.8 seconds left and no timeouts remaining. The Wizards' Michael Ruffin intercepted the full-court pass and tried to toss the ball high into the air so that the clock would run out. But the ball slipped from his hands and was not thrown high enough. There was still enough time on the clock as Peterson caught the ball and launched a "Hail Mary" three-pointer and sank it to send the game into overtime. Peterson only played 55 seconds in the game, with his first shift beginning with only 9.3 seconds left in the fourth quarter.^[1] The Raptors went on to defeat the Wizards, 123–118.^[2]

After signing Bryan Colangelo, it became apparent that the re-building process of the Raptors would not include Peterson. It was only a matter of time before his contract expired in the summer of 2007 that he would be gone.

New Orleans Hornets

On July 13, 2007, the New Orleans Hornets signed Peterson to a four-year contract, worth $23 million.^[3]

Charlotte Bobcats

On February 24, 2011, Peterson was traded to the Charlotte Bobcats along with D.J. White in exchange for Nazr Mohammed.^[5] He was waived four days later when his contract was bought out by the Bobcats.^[6] Peterson's final NBA game was played on December 12, 2010 in a 106 - 77 win over the Cleveland Cavaliers where he recorded 2 points.
