You do realize that Angelos didn't own the Orioles for the overwhelming majority of the time frame you reference, right? Or that Angelos didn't force TWO separate Senators teams to move, right? But whatever. Keep going with your delusional fantasy that the Orioles are the center of what plagues this particular DC baseball team.
It is true that Edward Bennett Williams (a Washington attorney, of all things) was the original villain of the piece, with his 'regional franchise' staying in Baltimore...but Angelos has escalated the matter.
