Houston is a bigger market than Seattle (#$ compared to #10), and their arena doesn't need renovations, so does Houston become the new favourite ?
Not sure if it would work in Houston, but I'm more skeptical of Seattle TBH. Milwaukee's got a new arena coming, but they would need an ownership group interested there. Quebec seems more likely for relocation at this point, but that may be a ways away.
