Jones played in 75 games, starting 24, for the Pacers during the 2004–05 season, averaging 4.9 points per game while also ranking 25th in the NBA and leading the team in three-point conversion percentage (39.8%). He saw increased playing time during the season as a result of a brawl between the Pacers and Detroit Pistons on November 19, 2004, that caused small forward Ron Artest to be suspended for the remainder of the season and shooting guard Stephen Jackson to be suspended 30 games. Jones was a DNP-CD in seven games. He scored a career-high 27 points on 10-of-14 shooting while going 6-of 9-from three-point range on November 28, 2004, against the Seattle SuperSonics.
