I dont think it is totally unreasonable to think the cubs would consider a move. A place like rosemont would and could give them the world to relocate. This a village that is getting huge revenue from a casino, hotels, convention center, entertainment complex and soon to be huge designer shopping mall. The village has no schools, library's etc to support. In essence this villages streets are lined in gold.
Someone mentioned the Sox moving after the lease expires in 2026, if the ownership at that time is the same as it currently it is, I would see them making the move. They love using other peoples money and this is a place where they would have the opportunity to do that.
