No reason, other than that they are popular team names. Kind of like wildcat mascots, or tigers and bulldogs. It is just a name that a lot of people seem to like.
I don't think there is any real official reason, just that they are popular. I don't believe it has anything to do with the history of the team or baseball. Hope this answered what you want.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
