I wanted them to keep the Joe and didn't like new arenas. Then I went to a game at the Staples Center, where in between periods you can actually go to the bathroom, get a beer and get back to your seat before the next period starts. Sight lines probably aren't quite as good as the Joe but they also don't have the death stairs.
To try and retrofit the Joe and bring it up to modern standards probably costs more than building a new one. Plus based on how they've talked about it, this is about much more than a new arena for the Wings. It would help create and expand an entertainment district downtown.
