High school

Quinn played his high school basketball at Dublin Coffman High School in Dublin, Ohio, where he set 14 school records and was named Columbus Dispatch Player of the Year in 2002. He was also twice named first-team all-state and was runner-up for Mr. Basketball honors in Ohio as a senior finishing behind NBA star Lebron James. Having also been named the Ohio Capital Conference Player of the Year, Quinn led his team to back-to-back conference championships, as well as two straight district championships.

College career

At the University of Notre Dame, Quinn was a three-year starter and two-time co-captain. He finished his career averaging 14.6 points, 3.5 assists, 2.7 rebounds and 1.27 steals per game. As a senior, he led the team in scoring (17.7 ppg), assists (6.4 apg) and was tied for first in steals (1.55 spg), while shooting 42 percent from three-point range. Quinn was a First Team All-Big East selection and also was a Big East Academic All-Star selection as a junior and freshman.

Professional career

Having not been selected in the 2006 NBA Draft, Quinn signed a partially guaranteed contract with the Miami Heat, and played for the team in the Orlando Summer League. During his first season, he played in 42 games and, in a February 5 bout against the Charlotte Bobcats, started his first ever game for the Heat, filling in for a suspended Gary Payton, and scored 14 points. He also dished 9 assists in an April 16 match against the Boston Celtics. During that first season, Quinn showed competent ballhandling skills and shooting touch, although he was left out of the Heat's playoff roster.

In 2007-08, with Payton's retirement and constant injuries to Dwyane Wade and Smush Parker, Quinn garnered more playing time, especially before the February trade that brought Marcus Banks from the Phoenix Suns. He scored a season-high 22 points against the Washington Wizards on December 13, connecting six three-point field goals.

Quinn scored a career high 26 points against the Detroit Pistons on April 15, 2009 on 9-of-13 shooting. He scored 19 of the Heat's last 30 points in the game.

On January 5, 2010, Quinn was traded along with a 2012 second round draft pick and cash to the New Jersey Nets for a conditional second round pick in 2010 NBA Draft.

In October 2010, Quinn joined the Philadelphia 76ers for training camp, but he was waived. He was signed by the San Antonio Spurs in November 2010.

On July 21, 2011, he joined the VTB United League club Khimki Moscow Region. In November 2012, he joined the Spanish League club Valencia. He then signed with the NBA D-League's Tulsa 66ers on December 28, 2012.

On March 20, 2013, Quinn was signed by the Cleveland Cavaliers for the rest of the 2012-13 NBA season.

On July 19, 2013, he was waived by the Cavaliers.

On Oct. 28, 2013, Quinn was hired by Northwestern coach Chris Collins to serve as the team’s new director of player development.
