Uhm, not sure where you get your information. (oddly, I've lived in most of these cities...)I have always found it amazing how people dump on Modell and the Ravens when other owners who ripped teams out of cities and don't suffer any repercussions in public opinion (Colts, Rams, Titans, Cardinals).
The city of Baltimore hates Indianapolis with a passion for stealing their team (a team they weren't supporting, by the way). Ask anyone in Baltimore about Mayflower, and you'll get an earful. (I'm from Indiana, and a Colts fan).
Georgia Frontiere is universally reviled for her horrible management of the Rams, and everyone was pissed when she moved them to St. Louis. Los Angeles loved their team, and she stole it away. Now that she's dead, there's hope that the team will come back. (I live in California now). Both the Rams and Colts are situations where the owners took the names and records with them when they moved, further pouring salt in the wound.
The Oilers/Titans is a bit different, because that move seemed amicable. The city at the time was in a depression and didn't want to build a new stadium, so Adams took the team to Tennessee. It worked out for Houston when they were able to build a new stadium and get an expansion team, and residents there love the Texans. (I lived in Houston during the final years of the Oilers). The team was renamed to the Titans, but kept the records.
The Cardinals have moved twice, but Chicago already had their team. St. Louis got the Rams a few years after the Cardinals left. I've never lived in St. Louis (but my sister does), so I don't know what the local feeling is for the Cardinals.
At least Cleveland was smart enough to force Modell to leave the records and name with the city when he stole the Browns. The Ravens are essentially an expansion franchise but with the players and front office from a previously established team.
