The wording for the blocker rule states that it "can be employed only one time per region, and only the first time it is necessary to do so. This process cannot be applied to the final at-large selection."
Hypothetically, suppose one region's teams (3rd-7th) has 8,10,2,11,12,13,14 points, respectively.
Another region has 9,9,9,9,9,7,7,7,7,7,7.
Supposing no team from another region has any points, and none of these teams will get points from wins against each other, what would be the order of selection for at large bids?
