For a battle royal, I feel like it would be the Eastern Confrence vs the Western Conference, they all start in their cities and walking only, will have to attack each conference's city. The Main contention cities for bot east and west would be New Orleans and Minnestoa for the west. As that is the first ilne of defense for the west. And Chicago and Atlanta for the east, as there most people would be joining them. For the eastern cities, Manhattan, Buffalo, and Baltimore would make the treck to Atlanta, with Tampa maybe arriving at the edge of florida to make sure they dont try to flank into florida. That owuld mean that TOR,HAM,NEW, and CHI would go to Chicago to face up against the northwest teams. I feel like the East would attack first, entering new orleans and try to attack with speed, as LAP and SFP is far away to walk from. Snatching up NOLA and TEX early would be a huge win for the eastern teams.

From there who knows,
