Let's start with two terms from game design: lame-duck and kingmaker. In a game with more than two players (or more than two teams), a "kingmaker" is someone who can, through his or her in-game actions, decide which OTHER player will win the game. The kingmaker is so far behind that he can't win, but he could deal a card (or whatever) to Alice or to Bob, which would determine the winner. This is considered really bad because you'd hope Alice or Bob would win off their own skills, not from some 3rd party's vote. "Lame-duck" (a term I use because I don't know what else to call it in game design) is the portion of a game where a certain player cannot possibly win anymore but somehow they are still stuck playing the game. Lame duck players are ripe to be kingmakers. When you don't have skin in the game anymore, so to speak, your potential to screw things up for others is pretty high. (Note that this is NOT what's going on the badminton case right now.)
