I am not sure about Giordano yet. I mean, if you look through the list of retired numbers (
http://icehockey.wikia.com/wiki/List...etired_numbers) there is a commonality about Stanley Cups and Olympic medals or multiples of each, and failing that, they were with the team for a long time.
And if being an occasional jerk is enough to not get your number retired, well, how about Grant Fuhr?
