Boucher enjoyed immense success in his first season, producing at a nearly point-per-game average and winning the QMJHL Rookie of the Year award.

His second season came with just as much success, as Boucher notched 77 points in 65 games with Granby and the Laval Titan, once again being named a second-team All-Star.

[citation needed] In Los Angeles, Boucher produced better numbers, but still proved unreliable to finish a complete 80+ game season in the NHL.

[citation needed] In 2002, Boucher signed as a free agent with the Dallas Stars, reuniting with the former special teams coach of the Kings, Dave Tippett.

[citation needed] During the 2008–09 season on November 16, 2008, Boucher was traded by the Stars to the Pittsburgh Penguins in return for Darryl Sydor.
