Just noticed your question on my talkpage — somehow I'd missed it.  My understanding of the WP convention is that if a player is rostered with a club for any significant period of time, that club is listed in his infobox even if the player makes no appearances for the club.  If a player only passes through briefly and makes no appearances for the club, however, it isn't listed.  As for the other question, I'd say it's fairly common in the US for a player to spend a very brief period on the roster of one club before being traded to another: for instance, in the 2006 expansion draft, expansion franchise Toronto FC snapped up a couple of guys simply for their "trade value" and then proceeded to deal them to other teams in exchange for players they actually wanted.  I believe that in circumstances like this, we wouldn't list a Toronto FC tenure in a player's infobox.  Overall, my understanding of the guidelines here is pretty shakey, to be honest.
