I first read "Team cards can link every player pictured as long as each player can be differentiated" the way Dan does (3:07pm timestamp), with "every" being the operative word. But I can also see how Tscastle reads it.
If Admin is willing to consider a revision, should the rule read: "Team cards should link to individual players only if every player on the card can be identified."
Or, if Tscastle is right on the intent "to allow us to link as many players as could be positively identified," should the rule read: "Team cards can link any player pictured as long as the player can be differentiated."
