Martin Biron of Lac St-Charles, Quebec starred with Trois-Rivieres in the QAAA before joining the Beauport Harfangs. After leading the QMJHL in 1994-95 with a 2.48 goals against average, Biron was placed on the league's First All-Star Team and was named the CHL Goaltender-of-the-Year. His fine season was capped off by being chosen 16th overall by the Buffalo Sabres at the 1995 Entry Draft.
Biron returned to junior in 1995-96 where he won 29 games again and helped the Harfangs reach the QMJHL final. The next year he battled injuries but still played 34 games for Beauport and the Hull Olympiques. The young netminder was impressive during his first year of pro hockey in 1997-98. Biron registered five shutouts in 41 games for the Rochester Americans along with a fine 2.93 goals against average. The next year he was virtually unbeatable when he led the AHL with a 2.07 goals against average, six shutouts and 20 playoff wins as the Amerks reached the Calder Cup final.
Following his outstanding year, Biron was named to the AHL First All-Star Team, won the Baz Bastien Memorial Trophy as the league's top netminder, and shared the Harry "Hap" Holmes Memorial Trophy with teammate Tom Draper for allowing the fewest goals during the regular season. The young phenom also played six games for Buffalo but the Sabres used Dwayne Roloson as Hasek's backup that year.
The talented backstopper won the backup role out of training camp in 1999 and ended up playing 41 games when Hasek was injured. He recorded five shutouts and won 19 in a solid rookie performance. His workload was reduced to 18 games the next year but he was expected to challenge for the starter's job after Hasek was traded prior to the 2001-02 season.
Since becoming the Sabres number one netminder, Biron went on to establish a career high 31 wins in 2001-02 before stumbling the following year. Although, Biron and the Sabres struggled, Team Canada added the Lac-Beauport, QC. native to its World Championship team that won gold at the 2003 Worlds. Comming off a tough season in 2002-03, Biron rebounded in 2003-04 with a 26-18-5 record.
Biron stood between the pipes as the starting netmidner in Buffalo for the next three consecutive years. In the 2005-06 season, Ryan Miller would take over as starting goaltender and quickly become one of the league's elite goaltenders, leaving Biron to serve as a back-up with the club throughout the remainder of his tenure.
The Sabres opted to send Biron to the Philadelphia Flyers at the 2007 NHL trading deadline in exchange for a 2007 2nd-round pick. As a Sabre, Biron went 134-115-29 since breaking into the NHL in 1998. He went on to finish his season with the struggling Flyers and sign to a two-year contract extension with the club.
In his first full season in Philadelphia, Biron recorded 30 wins and led the Flyers to the Eastern Conference Finals. However, the club was ousted by their cross-state rival Pittsburgh Penguins in just five games.
As an unrestricted free agent in the summer of 2009, Biron signed on with the New York Islanders, joining existing goalkeeper Rick DiPietro and fellow unrestricted free agent signing Dwayne Roloson.
On July 1, 2010, Biron was on the move again. This time however, he wouldn't travel far, joining the rival Rangers as an unrestricted free agent.
