Montreal is now ahead of Seattle averaging about 40,000 a game.
Hanauer told the Seattle Times: "It's exciting. It's exciting for the league. I don't think they'll stay there very long, which is unfortunate.
"Again, big crowds, more excitement and more engagement within the league is just a good thing. I'm very happy with our 39,000 per game, so if somebody gets to 42- or 44- or 46 (thousand), we'll try to compete and our fans, I'm sure, will take that as a challenge. But ultimately, it's good. It's a good thing."
