*I do not know if/how the Old BEast shares were distributed to the new members (XU, CU, BU), but I heard straight from the horse's mouth that the Big East did keep those shares earned by current BEast teams, not the AAC, as was widely reported.
** I still don't have proof of how the shares are currently distributed, but have heard from reliable peeps that it's an equal distribution, so that's what I assumed for that article.
