Some years ago in Brazil, the CBF the league body through a case in court lost the right to organize the season for the year. The court dispute was between the CBF and a team that was supposed to be relegated to the second division the upcoming year, they got the relegation spot in a really unfair fashion. The top clubs have an association to negotiate for media rights etc called the Club of 13. Seeing as there couldn't be an official season, this association organized their own tournament. As to not have any bullshit controversy they created a giant league of 116 teams, basically all the teams of the first, second and third division in one big giant tournament. All of Brazil unified in one. It was very fun, the little guys and the big guys, giant killers, huge upsets, lots of flashy play. After, most everybody agreed in was a great experiment. To the finals it reached a team from the suppose second division and one from the first who had the best player in the country at the time. Lots of little guys had great runs.
Lots of talent surfaced that year. It worked well down there, and in soccer, as not much is needed to get a rising star in the game. I don't think it could work in North America with all the refinement needed to reach the big leagues. The following year the Club of 13 let the CBF handle the season going back to the regular style with a 28 team first division. The subsequent years they would cut off 2 teams from the league until they ended with a 20 team league format like it's the world standard in soccer. Now a days they have something similar called the Brazil Cup, teams from all over but it's not quite the same with only head to head elimination format. It's one of the best tournament to bet (imo wally).
