Giants Stadium and Pontiac Stadium. They also used Orlando, which had grass then but FieldTurf now.
In Arizona, only U. of Phoenix Stadium is a realistic option. They're not going to play Cup games outdoors in 100+ temperatures, not even at night.
Baltimore's football stadium went back to grass this year, so it could host. The Redskins might have a new stadium in DC by 2026.
Cleveland didn't host in 1994, as the Mistake by the Lake was still in use. It could host in 2026. Pittsburgh is another possibility, as is Columbus (Ohio Stadium, which would need palletized grass).
When the Crew were playing there, they had the narrowest field in MLS.
But I would expect them to stick with large stadia in major metro areas and not venture into college stadiums.
I would expect no more than 16 sites, though LA could certainly host two pods. And Baltimore-Washington could also easily host two pods.
I'd be shocked to see Cleveland and Pittsburgh get games at the expense of other larger metro areas.
I think they would struggle to sell 108K tickets for two group round matches.
