... The 3 Team Tokens that are supposed to be used to mark Star Players from another team should you get them are better used to simply mark the Match-Up on the side of the card you are contesting. Whenever you commit your first player to an end-zone on a match-up, simply take your Team Token and place it on the match-up card so that it sits just above your first committed player but be sure you don't cover up the payout section of the card.
Yeah, that's the way I've always played it. It just seemed a lot more efficient and clear to mark all the matchups rather than specific cards.
