I could definitely see a Chivas scenario where this team folds or is relocated, and The Smurfs are the only show in town for a few seasons. Let em languish in RBA/YS purgatory while the new NY1 club comes together for a well-done, well-hyped relaunch appropriate to and competitive with 2022/3/4/5 MLS.
Unlike Chivas this is a founding club so I don't think the wait would be four years for Metro 96. That interim period would be angsty as hell though.
I also see a Columbus Crew scenario where RB sells the team and the new owner moves the team to Vegas, El Paso, Sacramento, Detroit or something. The only difference is that there wouldn't be enough outcry from the fans to get a replacement team, and NYCFC would then become the full-time tenants. At this point, I don't know how much I'd care, as long as they don't erase my name off of the rock in front of the stadium (vague reference alert).
