They should never have been allowed to leave. Art Modell argued against expansion to Baltimore, then cut off stadium negotiations with Cleveland. Then he got a state-built, rent-free stadium from the people of Maryland.
to make it worse, when the Ravens arrived, Orioles owner Peter Angelos (a piece of human debris if there ever was one) invoked the "parity clause" in the Orioles lease at Camden Yards to get out of paying any more rent to the state.
I guess this was Parris Glendening's gift to Baltimore for stealing enough votes to get him elected.
I did like the old Baltimore Colts and Cleveland Browns. Sad what was done.
