Bettman just wants to make an NHL team the first of its kind, that's why he pushed Vegas so hard and approved the Columbus Blue Jackets despite their nice arena, Nashville despite the fact they had just gotten the Tennessee Titans as well. I think that's why he's eyeing Austin, but as I somewhat agree to this because the attendance would be much higher in Austin as opposed to Houston, which would lead onto Houston's interest in an NHL team. It's questionable whether or not Houston could work out or not.
This is why I want Portland to get an NHL team, all they have is NBA there and think they could support a hockey team despite Seattle being 3 hours away. Also, Quebec because they would give the Nordiques terrific support, same with Hartford.
Problem with the Whalers was their arena.
