The definition of "elimination game" is pathetically simple: if you lose, your season's over. If you win, your season continues. That's it. It doesn't require both teams to be in that situation. It doesn't have anything to do with tie rules or seeding or anything else. Individual QBs/teams "elimination game" records only require that that team be in the situation of knowing that their season ends if they lose. What happens to the opponent's season is one million percent irrelevant. So in Cowboys elimination games where Romo was the QB, the record is 1-6.
