With a team that has as storied of history as the Toronto Maple Leafs, pretty much every single number has been worn by a Maple Leaf. From 1-99, only a few numbers have never been worn by a Maple Leaf: 66, 68, 69, 70, 76, 79, 86, 87, and 95.
While goaltender Dennis Hildeby will not be taking any of these numbers, Hildeby will be taking the number 41 which has been worn by only 8 other Toronto Maple Leafs. However, none of those players were goaltenders which means Hildeby is officially the first goaltender in Toronto Maple Leafs history to wear the number 41.
The other 8 players to wear #41 are Paul Gagné, Eric Lacroix, Shayne Toporowski, Matt Stajan, Jason Allison, Nikolai Kulemin, Nikita Soshnikov, and most recently, Dmytro Timashov. Kulemin wore the number the longest wearing it from 2009-2014.
