One note about the Golden Knights - they immediately were a good team so they gained fans super fast who might not have been tune into the NHL by winning. When the Stars moved to Dallas, they had a similar experience.
The A's blow. It won't have the chance to draw immediate new fans.
Sucks for As fans, but clearly the city doesn't want them and the team doesn't want to be there. TB, you're next.
As a Tampeno, I feel compelled to defend Rays fans. Stu Sternberg and his ownership is an abomination. He's been trying to bilk the cities (he's been playing Tampa and St. Pete against each other) for a decade but no one's falling for his bullshit. The stadium was built BY THE CITY (!) BEFORE a team was even here, and frankly that's laudable. That the team hasn't built a new stadium in 30 years just reflects poorly on Sternberg, who's owned the team since 2004 (!!).
For anyone who isn't familiar, St. Pete is a gulf-coast city surrounded by water on 3 sides, and is considerably smaller than the more corporate sister city in Tampa. The team should absolutely play in Tampa, and a group of locals put together the parcels for a new stadium right in downtown Tampa a few years ago, but then Sternberg asked the local govt's to pay for a $1B stadium and everyone threw their hands up and told Stu to go fuck himself. That was absolutely the right call.
The stadium lease is set to expire in a couple of years, and it's a huge urban development story here. Basically, St. Pete has matured a great deal in recent years and the land would be much more valuable to the city as a generic development rather than a stadium. It was also built on top of a historical black community (a really sordid pattern in the area--don't get me started on the development over black cemeteries), and the black mayor of St. Pete is doing really commendable work on bringing attention to this often overlooked fact. Nevertheless, Stu is still courting both cities while still threatening to relocate elsewhere while he tries to squeeze every penny out of local gov't. The guy is tone deaf beyond belief--the Montreal/Tampa split plan was asinine.
The club is finally old enough that kids who grew up with the then-new franchise are having kids and raising them as Rays fans. If they can figure out a way to stay here for even another 5-10 years, that should provide a real boon.
I'll leave you all with this--2019 primetime viewership by club:
As far as I can tell, this doesn't look at percentages, but rather raw numbers. So the Yankees get credit for the millions of viewers they garner, but the data isn't presented as people tuning in for Yankees vs. Knicks, or other content. In any event, Tampa clocks in at 57 (in 1000s). The A's were at 21. Miami was at 15 (ooof). Tampa was higher than Seattle, Denver, Phoenix, Pittsburgh, Detroit, Dallas, KC, Cincy, Baltimore, San Diego, and the White Sox. The problem is with Stu, and the stadium.
