If Ricketts had the slightest intention of ever moving the team and an ounce of sense, he would have had serious exploratory talks with whatever suburbs would talk to him and kept that going while he went to the city to try to convince them to fund the renovations three years ago. Since he didn't, and the best case he had was "Please? You did it for other people. Come on, be cool," we can safely assume that he knows it's not really a viable option and his bluff would be called quickly and embarrassingly if he did more than vaguely hint at the prospect.
