Coreau made 11 starts in December and finished with a 9–2–0 record with a 1.92 GAA and a .938 save percentage during a historic month for the Griffins. Grand Rapids extended its franchise-record winning streak to 15 games in December before a 3–2 defeat at Lake Erie on December 27 halted the run. The Griffins concluded December with a 10–2–0–0 record, marking the best December winning percentage in the franchise's history.
