It has been suggested that we have a 3 team championship game . . . i have to beat 2 teams to win 1st which sucks.
This is not really fair to you. You've earned the right to be in the final game and face ONE team. It is your commish's fault that your league doesn't know who that team is yet. The suggestion offered is reasonable. If you don't want to play an unknown opponent in the final game, which seems kind of weird, then here are other ideas:
1. Coin Flip to determine who won the other semi final
2. Put a poll here on the Cafe for which positions should break your tie, and use H2H at each position to break it. In other words, poll the cafe anonymously, and if they vote to use QB, then compare QB to QB points, and use that as the tiebreaker from last week. As long as no one here at the cafe knows your league members or their rosters, it's pretty fair.
