Personally, I find this gesture incredible, and even though thousands of people have his jersey with the number 22, it remains a very good reason for the change.
The NHL and Gary Bettman, however, have a say in such situations, as the deadline for changing numbers had passed for Cole Caufield.
It's a very nice gesture from both the player and the league, which decided to make an exception for a very good reason. Small players always struggle to make their mark in the NHL, and Johnny Hockey inspired many small players like Cole Caufield to believe in their dreams.
