Forgot to post mine. I wear 75 simply because when I started playing the league I was in had the same home and away jerseys for everyone, white or red. Inevitably as players moved around from team to team you would have two or three 10s, 9s, 19s, etc ending up on the same team. I picked a number that no one used (until Brett Lindros) so that no matter what team I was on my number wasn’t duplicated.
Other numbers I have been issued are: 4, 5, 9, and 15.
