You are missing the point. There needs to be a defined structure. They should be selected as the 1800's Baltimore Orioles and used as a stand alone franchise. I have found a way to include them in my Multi-Franchise League. They have been selected multiple times in every season.
The only thing that is the same is the name. By your argument, why can't ANYONE take them? Since they are not related to the Rangers, but maybe they should take them as it would be sad not to have them. Maybe the Rangers should get Walter Johnson since they were once called the Senators?
they are just as related to the New York Yankees as they are to the current Baltimore Orioles.
You see, this just turns into Chaos if you do not follow the rules.
