Taiwo Atieno II 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 Defender of Open Editing
