[Jack Jones]

Not enough choices.
You forgot these:

• B sandbags C, meanwhile X dumps on A so that Y gets #1 seed and chooses Z and W and gives X an IOU.

• B sandbags C, but the scoring software gives them the win by mistake, causing B to protest their win and everyone else to detest B, but not by mistake.

• The US invades Canada mid April for NAFTA violations (at least that's the excuse given) and the Champs end up being played late July in Hamilton, Ontario because the Triplets aligned with Woburn and took out the first wave of Bradleys then a division of M1A1s.

• The Martians invade Atlanta but are done in by the common cold (great idea for a radio script), meanwhile all the scheming and dealing backfire into causing a Championship alliance made up of the three teams from New Mexico who conspired when no one was looking.
