ICYMI: Mitch Marner began using the new True Project X stick over the weekend. An additional note about Marner: He did not, and likely will never, use the Catalyst 9X3 in a game. We only ever saw him with a 9X3 at All-Star festivities last season. 📸: @nhl #leafsforever #truesday #true #hockey #toronto #mapleleafs #mitchmarner #projectx #hockeysticks
