Of course it's speculation. It's speculation because the NHL DOESN'T have to do anything.
The Coyotes have played in Mullet for two season without owning any land. The auction changes nothing if they lose. The NHL accepted Mullet as a temporary situation, and it's the owner who's on the hook, not the NHL.
Half of what's said in these threads aren't logic-based, but what people want to see happen, including the hockey media. "When is enough enough?" has been asked for 15 years, and the answer has always been "it's enough when the owner has had enough."
But you've got the same guys saying the announcement might not wait til the auction, we might hear on April 18th! Which makes even less sense.
SOMETHING has to drastically change the calculus. The NHL making an about-face is not very likely. "Bettman works for the owners" is thrown around all the time... so, he's gonna take a team from an owner? An owner he kind of recruited?
AM is not behaving like someone who's done and wants out. He's still trying to make it work, which the NHL craved for so long in Phoenix.
But expansion to SLC and ATL changes the calculus. It creates a situation where the NHL can keep the PHX owner who wants to make it work, but not suffer through Mullett for 3-5 years when the Delta Center is right there. That makes the most sense by far.
