Out of curiosity, what cities do you think are possible landing spots, that could have a MLB caliber stadium for them to play in next season?
I'm all for speculating that this is John's secret agenda. I'll even entertain the idea that he has already been in clandestine discussions with political leadership in one or more cities/states. But the destination would have to be a former MLB site, like Montreal or Dallas/Ft Worth, until a new ballpark is completed. But that would be an expensive and unnecessary layover. The smarter move would be to sign the 5 yr lease, then get to work finalizing a deal to move to his preferred city. That gives MLB plenty of time to approve the move, the destination city has plenty of time to secure a site and financing for the new palace. Meanwhile in Baltimore, attendance may drop off, but they're already use to small crowds, so it's not like he'll be shooting himself in the foot for the short term.
I'll mention this again. Wanting to move, and having somewhere to move, are two very different things.
I mentioned earlier that Montreal is the only place off the top of my head that has both a serviceable temporary facility as well as being on the potential list of cities for relocation/expansion (meaning a new stadium could get done if they know a team is coming).
My assumption is that at this point John sees no need to start fanning those flames yet in his leverage play. The uproar that has already been created simply by not picking up the extension may be enough to get the state to concede what he wants. But if summer rolls around and John doesn't feel enough headway has been made, especially with new leadership in the MSA, then I would not be at all surprised to start hearing rumors.
