B3 is a tournament that is used to determine which team is the best in te world, now it may have it's flaws but that is still it's function. I think the world rank should reflect that. My idea would be that whoever wins b3 would receive the necessary amount of points to become the number 1 team in the world. Otherwise isn't the function of b3 compromised?
if you are in a constant way close to it, you maybe still considered as the top team even when you don't win the thing. If you would ask me which team is the best soccer club, i would probadly go for Barca or Real and not Milan(i would even mention some english team before then).
And the results of the BBB tournament have a big impact into the world ranking.
