They are hoping some desperate town will want to just make their dreams come true with the stadium.
Mayor of Pawtucket wants to talk to the state about what could be done to McCoy with a smaller amount of state money. But this is largely symbolic at this point, I'm sure Grebien would like to keep the PawSox but as noted earlier, the city could probably get better use out of the land. So it wouldn't be a huge loss if they went. It might be a bigger loss for the state if they leave the state I guess?
I have heard the Worcester is not really eager to jump in the stadium building business, similar actions have been killed in Springfield in the past, even for AA stadium.
New Bedford really would like to be considered, and they are building a nice area around the whaling museum, but I don't see Mass giving them the money or having the money themselves.
I think they missed their chance to jump on Hartford and the political climate there.
The thing about Pawtucket is that it is a little of a pain to get to but at least Central to a large population. Warwick is interesting only because they tend to have money from the airport and they have some federal money to develop around the newly built train station and transit center, though I'm not sure there is space for a stadium in that area, really. And if it is not walkable from the transit center I just don't see the point. Beyond that, Warwick might make it more attractive from families and businesses from southern RI to get to games, but it cuts off almost everyone north of Providence because of the traffic, etc., and the population and business base is just much better in southern Mass than Southern RI. So while Warwick may be able to get stadium numbers to work, I'm not sure they would get the sales that you would get in Providence or even staying in the bucket.
So what else might happen? To be honest, while I am opposed to the public $$$ I thought they picked essentially the best site in Providence. There are plenty of other holes in the city, but the land acquisition to get a site large enough for a stadium plus parking would be really hard, and certainly not going to be a central location. You could maybe try to buy some of the land from JWU harborside (where they have their athletic fields) but that would be a tough area for traffic so they would probably have to ask for infrastructure as well. I definitely don't think you want to put it in the middle of the industrial waterfront. You could maybe get it in Gano Park if you take all the buildings along Gano St., but it would be a tight fit and there would be no ancillary parking, I don't even know if the site can support a building, and getting the city to give up a park given the initial response to this stadium might be pretty hard.
