We normally don't categorize a profile to the entire league unless they were a founder or something, so I am adding the category for the team he was part of. Also, it looks like this person is a notable, so you should add the notables project as a co-manager. He's a living notable.

You should add [[Category: Vancouver Whitecaps (1974–1984]] to his profile.
Also, since the sport is known as soccer in North America, I am adding [[Category:Soccer Players]]
