2006-07: Including the WHL playoffs, Sexsmith collected 14 shutouts in 73 games after being handed the starting job by head coach Don Hay in November. Had a sparkling 1.79 GAA. After veteran goaltender Dustin Slade left the Giants, Sexsmith weathered the media storms and doubts concerning the ability of a 17-year-old being able to backstop the Memorial Cup host team. The critics have been answered and silenced as Sexsmith gained confidence throughout the season and led the team to a national championship. The 6', 200-pound native of Priddis, Alberta will be tested next season in Vancouver as the Giants look to reload following the loss of some key veterans.

WHL-based Sharks scout Brian Gross on Sexsmith (2009): “Tyson had a solid season and playoffs for a young player as he led his team all the way to the Memorial Cup,” Gross said. “He is unflappable, hates to be scored on and lose, and never blamed his teammates. He was always in position for the first shot and never gave up on a play. He showed excellent technical skills and a great glove hand and he was strong physically.”
