New Orleans - Jarrett Jack's first regular-season start since the Chris Paul trade was more than good enough for the New Orleans Hornets.

Jack had 21 points and nine assists in his season debut, and New Orleans dominated in its home opener, beating the winless Boston Celtics 97-78 on Wednesday night.

The Celtics are 0-3 for the first time since 2006-07, the season before they traded to bring Kevin Garnett and Ray Allen in to help star Paul Pierce. Pierce has yet to play this season because of a bruised right heel.

The Hornets, meanwhile, were without Eric Gordon, who bruised his right knee in a season-opening win at Phoenix in which he scored a team-high 20 points.

Jack did not play in the win over the Suns on Monday night because of a one-game suspension stemming from a drunken driving arrest last season. His return helped a Hornets squad looking for a boost in Gordon's absence, and power forward Carl Landry pitched in with 20 points and 11 rebounds.

Allen led Boston with 15 points.

Jack inherited the Hornets' starting point guard job in the preseason after Paul, a four-time All-Star, was traded to the Los Angeles Clippers for Gordon, Chris Kaman, and Al-Farouq Aminu.

Kaman, who had 10 points and five rebounds off the bench in his Hornets debut Monday, came back with 12 points, nine rebounds and three blocked shots against Boston.

Kaman backed up Emeka Okafor, who had 13 points, six rebounds and five blocks.
