I'm on a hockey forum with a similar thread and my criteria is always: you associate a player with one or two teams during his career, and at the end of his career he plays for one or a few different teams for a brief time and looks completely out of place in that uniform. For me, criteria that do not apply are pics of the player in pre-NHL uniforms (minors, pee-wee, etc.) or in international competition uniforms, or in old-timer or similar charity event uniforms. I also do allow for WHA uniforms.
I haven't read through the whole thread yet so I hope some of my postings aren't duplicates, but I have many...
