Inspired by this post and this reply: across all sports, what are the worst tournament design blunders?
To get us going, here are a few examples of what I'm after:
To get us going, here are a few examples of what I'm after:
- the UEFA Euro tournaments now offer two paths of qualification: the one via the standard qualification groups, the other via the Nations League. Of all the teams that do not qualify through the standard qualification groups, the eight ones that ranked highest in the Nations League will participate in playoffs for further qualification spots. Now, Ireland find themselves in the position that they cannot qualify through their standard group anymore, but they are on the fault line of playoff qualification by virtue of their Nations League ranking. From their standard group, either the Netherlands or Greece will qualify directly. In the Nations League ranking, the Netherlands ranked above Ireland who ranked above Greece. Hence, it is in Ireland's direct best interest to lose their qualification group match to the Netherlands, so that the latter maximize the chance to qualify directly from the group which takes them out from above Ireland in the playoff qualification ranking, hence maximizing the chance that Ireland will qualify for the playoffs. Lose to win!
- the current Rugby World Cup has two systems that might individually still make sense, but in combination can lead to proper weird shit. On the one hand, there are bonus points to be had in each pool match: scoring four or more tries begets you one, and losing by at most seven points begets you another. On the other hand, the tie breaker system went in waves: if there was a three-or-more-way tie in the pool stage, one would first go through all the tie breaking criteria until a highest-ranked team was determined; subsequently, the remaining teams will have their tie broken using all the criteria again from the top. Results among the top teams was the first criterion; points difference was the second. So if A beats B, B beats C, and C beats A, the winner is determined on points difference, but whoever ranks second and third in points difference doesn't matter; those places are determined by the winner of the match between only those two teams. This led to a very contrived but still mathematically possible scenario where, if the last pool game went in a particular direction, Ireland would qualify for the knockout phase by either scoring or conceding a converted try, but be eliminated if the score stayed the same. Any movement wins, inertia loses!
- similarly, Barbados-Grenada in the 1994 Caribbean Cup qualification ended with a team that would benefit from scoring in either goal. A variant of the golden goal rule in extra time was implemented, where the goal would not only decide the match but also be worth two goals. Barbados was leading 2-1, but needed to win the match by two goals to qualify; Grenada would qualify with a single-goal defeat. So Barbados deliberately scored an own goal to level the game. Now Grenada would qualify if another goal was scored in either goal, but this didn't happen, and Barbados picked up the double-counting golden goal in extra time to qualify.
- in the group phase, in each group, two teams were seeded and two unseeded. The seeded teams only played the unseeded teams; seeded teams didn't play each other, nor did unseeded teams. So, each team only played two group matches. In case of a tie in points for second place in the group, those two teams meet in a playoff. Result: if you're an unseeded team, and you end up in a group with Brazil (seeded) and Gibraltar (unseeded), you are going to have to beat the other seeded team in your group not once but twice in order to qualify out of the group. This exact scenario happened in two out of four groups.
- in the knockout phase, the bracket was not predefined. Instead, each round was drawn stratified randomly: in the quarter finals, teams from group 1 were drawn against a random team from group 2, and teams from group 3 were drawn against a random team from group 4. The semi finals were randomly drawn such that each match contained one team from groups 1 and 2 and one team from groups 3 and 4. Random draws sound completely fair before you actually make them, but the coins were flipped in such a way that all the group winners ended up in one half of the draw, and all the group runners-up in the other half of the draw. So, fair principle, least fair possible outcome.
