 With the departure of team captain Spencer Machacek to the professional ranks the following season, Blum was chosen in his place for the 2008 – 09 season. He began the season with 14 points in his first 10 games and was named WHL Player of the Month for September / October. On November 19, 2008, he recorded his first career WHL hat trick in a 4 – 1 win against the Chilliwack Bruins. Later that season, on February 7, 2009, during a 4 – 2 victory over the Portland Winter Hawks, Blum became the Giants'all-time assists leader with his 148th assist to pass Adam Courchaine's 147-assists mark. Nearly a week later, however, he was sidelined with a shoulder injury after receiving a couple of hits from Kelowna Rockets forward Jamie Benn in a 3 – 2 overtime loss.
