Schenn, who was originally drafted by the Leafs with the 5th overall pick in the 2008 NHL Entry Draft, has worn #2 for the majority of his career, minus the 4 years he spent in Philadelphia when he wore #22 and the year he spent in Los Angeles when he wore #52. However, with the recently acquired McCabe having already opted for #2, Schenn has opted to return to #22, which was last worn by Zach Bogosian (2021).
Meanwhile, Gustafsson has worn #56 for much of his career, aside from brief stints wearing #52 and #32. With #56 currently available in Toronto, Gus will continue on with that number during his time with the Leafs. The number was last worn by Kristians Rubins (2022).
