I have two questions regarding jersey number:
1. Why do goalies tend to wear numbers around 30 (for example,
Roy wears 33, Potvin wears 29 etc.)? I can understand that some of them
wear 1 because goaltenders in soccer usually wear 1.
2. Was there any player (in the NHL) wearing 99 or 66 before
Gretzky and Lemieux started wearing them?
