David Heasman anchored NAU's offensive line from 1994 to 1998, helping Northern Arizona reach the Division I FCS Playoffs for the first time in program history in 1996. A four-year starter and letterwinner, Heasman earned All-Big Sky recognition in both 1996 and 1997 as a guard.

"Being inducted into the NAU Athletics Hall of Fame is an absolute honor for me. NAU provided me with an amazing opportunity to grow and develop as an athlete, individual and student. I was privileged to have a great professional career on the field as well as off the field, which is a testament to my time at NAU," said Heasman. "Flagstaff and NAU hold a special place in my heart, and I couldn't be prouder to be inducted next to fellow teammates and many other Lumberjack greats who have been a part of the Hall of Fame journey."
 
During his time as a Lumberjack, Heasman blocked and protected a pair of quarterbacks in Jeff Lewis and Travis Brown. He was instrumental in guiding running back Archie Amerson to win the 1996 Walter Payton Award. With Heasman at guard, Amerson became NAU's all-time leading rusher with 3,196 career rushing yards in just two seasons. Amerson still owns the Division I FCS record for single-game rushing touchdowns (7), single-game total touchdowns (7), points scored in a game (42), single-season rushing touchdowns (25) and single-season all-purpose yards (2,249).
 
Heasman originally hails from Canada and was a standout in the classroom as well. He was named to the Athletic Director Honor Role in 1996, 1997 and 1998. After being drafted as a junior to the Edmonton Eskimos of the Canadian Football League (CFL), he still graduated on time from NAU's College of Business with a degree in marketing management. At graduation, he was selected to be the Standard Bearer for the College of Business graduation ceremony.
 
Heasman's success continued after his time as a Lumberjack concluded, as he played for three different CFL teams from 1998 to 2004. He played in 117 regular season games and eight playoff games, including four Western Division Finals. In 2001, he won a Grey Cup championship with the Calgary Stampeders and made a return to the Grey Cup in 2004 with the Lions.
