The Leafs signed Nicolas Mattinen in April, marking a significant return for the defenseman who was originally drafted by Toronto eight years ago. At 225 pounds, Mattinen brings a substantial physical presence to the defense. His recent performances in the AHL, U-Sports, and the DEL have been impressive, with two stellar seasons that saw him accumulate 88 points in 98 games.
With the Leafs currently having a full roster, Mattinen is expected to start the season with the Toronto Marlies in the AHL. However, given his impressive recent form and the Leafs' need for a right-handed defenseman of his caliber, he could be one of the first called up in case of injuries or other roster changes.
