Holmberg had been a mainstay for the Leafs most of the season until the Leafs brought in O'Reilly,
Noel Acciari and
Sam Lafferty, which left Holmberg without a spot in the lineup. It led to Holmberg being sent down to continue to get playing time. In 36 games with the Leafs this season, Holmberg has registered 5 goals and 13 points while playing in a bottom-six role where he seemed to have earned Sheldon Keefe's trust and was relied on defensively at times.
