Yes, the listing for Anaheim Mighty Ducks is wrong.
Regarding the Cleveland Browns, and the Charlotte Hornets, they are two different teams regardless of whatever hoops their respective leagues have jumped through trying to get you to think otherwise. Anybody needs to just check the actual records and it's obvious.
The point about getting them listed correctly thought that Ed made is spot on. We all know it wouldn't work, and would probably just make things worse. I get why it's done the way it is, but it'd not perfect. I go through great pains to make sure they are listed accurately in my listings and on the Cardboard History Gallery.
It's also why I can't really use the stats for teams on here. For the aforementioned Ottawa Senators 1 I have only one card, so that's easy enough. When you get to the Winnipeg Jets and the Charlotte Hornets, where I have hundreds of cards from both teams that used the name it gets much harder.
The teams changing leagues, if it's the same team, should not get another TID. Teams change leagues all the time, especially European teams where relegation is a regular feature of their entire sport. If the name changes, however, that's a different story and absolutely gets a new TID. Example: New England Whalers in WHA becoming Hartford Whalers in NHL.
VERY slow trading due to health problems. Not transferrable so safe to trade with, just moving is painful and can't always access the cards.
