I think that the move from Cleveland to Baltimore was handled poorly and just plain stupid, but the Dodgers move from Brooklyn to LA will forever be part of the team's history...then again, one of the top 10 biggest media markets losing a professional team SEVERAL times is rather crazy as well!
How could you forget the Colts leaving Baltimore to go to Indianapolis. Thats the worst team relocation because Isray (sp?) stole our team in the middle of night, after he said again and again that he wasn't going to move them. Oh, as I recall, the Browns got to keep their name, and history. They still are the Cleveland Browns. We lost our name [Colts] and history, so now anyone associated with the Colts is automaticly thought to be from Indy.
if i woke up one morning and found out that Pat Bowlen moved the Broncos to another state i would probably take the first plane to the city they moved to and start burning the stadium down, they cant take a city's team away and not expect some sort of retaliation.
but out of the ones you listed i picked moving the Raiders to Oakland. they should have just got rid of the team, it makes way more sense.
