Rodier brought up a good point though that Smith publicly brought up his push for an NHL team and the league normally would have frowned on it….. but not this time.
I think there's a number of explanations for this.
I mean, the elephant in the room, and the big conspiracy theory, is that the timing of the release acted as a distraction, be it coincidental or deliberate, from the SA cases related to Hockey Canada.
Another thing to consider, with the press release, is Smith kinda spoke up for all prospective ownerships in at least the four leading markets with interest in a team by asking for the application process to be opened. He doesn't explicitly state he's gunning for a relocation, that's only what people think when he mentions being ready for one. It's really a pretty ambiguous statement, to be sure, but one I personally feel like people are making too big a deal out of.
Lastly, I think the league is more amenable to a potential owner expressing public interest than recent history suggests, it just depends on who that potential owner is, and what antics they're employing (or, at the very least, not disavowing themselves from) in an effort to make that push. A good example of that would be the fans in QC boarding buses and visiting Nassau Coliseum to cheer for the relocation of the Islanders (or the Thrashers) to their town. Or, consider Balsillie's antics in trying to get a team in Hamilton. The league seemingly wouldn't discuss expansion with him, so he sought out owners and offered the keys to the vault. In the end, Balsillie found himself blacklisted by the league, and for good reason.
At the end of the day, it's certainly an interesting question, but I also feel like it's a bit overblown if one looks at the circumstances of prior incidents with potential owners. I think Smith is kinda skirting the line with the press release, but the examples above are predatory, and the league absolutely doesn't like that nonsense.
