On July 24, 2012, Prigioni signed a one-year contract with the New York Knicks for the rookie minimum.At age 35, Prigioni became the oldest NBA rookie in history when he made his debut on November 2, 2012. He became the team's starting point guard for the last two months of the 2012–13 season, as well as for the playoffs. In Game 6 of the New York Knicks' first round playoff series against the Boston Celtics, Prigioni made 3 three-pointers in the first quarter. The Knicks won 88-80 to advance to the second round of the playoffs for the first time in 13 years. On February 19, 2015, Prigioni was traded to the Houston Rockets in exchange for Alexey Shved and two second-round picks. On July 20, 2015, the Rockets traded Prigioni, Joey Dorsey, Nick Johnson, Kostas Papanikolaou, a 2016 first round draft pick, and cash considerations to the Denver Nuggets in exchange for Ty Lawson and a 2017 second round draft pick. Prigioni was immediately waived by Denver upon being acquired. On August 3, 2015, Prigioni signed with the Los Angeles Clippers.On January 13, 2016, he had a career-high eight steals against the Miami Heat, one shy of the franchise record held by his coach, Doc Rivers. On April 8, 2016, he recorded a season-high 13 points, a career-high seven rebounds, and a season-high seven assists in a 102–99 overtime win over the Utah Jazz. He had a season high seven assists against the Jazz. I love this signing.
Love Prigioni! Damn he is a tough, great effort player. The way he embarrassed the Clips in the playoffs was just beautiful!
