Just seems a little too far north for me. Will probably be one of those arenas that gets the "middle of nowhere, nothing else to do, no postgame/pregame dining" etc designations. I agree that suburbs would be better for a hockey fanbase than downtown Atlanta but this one just seems too far and I feel like they're going to get the same criticism that the Glendale arena and the Sunrise arena has gotten.
See post 287. That map is what the Braves presented when showing one of the many reasons for moving to the northern burbs. It shows who has bought tickets to games over the last several years. Since that move, their attendance has gone up and their development is a HUGE success. I'm betting the Gathering is using similar data.
To my definitely-not-an-expert eye, living in the Phoenix area, the Glendale situation was somewhat tri-fold:
1) Farther away from the bigger populations
-Gilbert/Chandler/Mesa/Tempe population is about 1.2M, (Scottsdale is another 240k)
-Glendale/Peoria/Surprise/whatever is less than half that
2) The money/disposable income is more abundant in the East Valley (Gilbert/Chandler/etc)
3) Demographically speaking, a higher percentage of the NHL's market lives in the East Valley than in the Glendale area
Bonus 4): The team never had a competent owner and GM who built any sustained success, which would be difficult for any market to overcome
I've never even been to Atlanta, but just based on some cursory research, 2 and 3 aren't going to be an issue in Forsyth County, and while there may be less of a population in Forsyth County than in downtown Atlanta, it's not just about raw population numbers (which is why 2 and 3 carry a vast majority of the weight). As a bonus, with the idea being that they'll have a competent owner and GM willing to commit to the teams success on the ice this time, and the new expansion draft rules that allow teams to be much more competitive much sooner, it shouldn't really be much of an issue.
Not to mention from a pure DMA standpoint, Atlanta is massive, encompassing Georgia, South Carolina, Alabama, and at least parts of Mississippi, Tennessee, and maybe North Carolina and northern Florida.
There's a reason the NHL wants to try Atlanta again. If it's succeeds it's one of the biggest sports markets in the continent. Certainly bigger than most Canadian markets, let alone the ones without an NHL team. It's bigger than Houston and Salt Lake City that people keep clamoring for. It's bigger than Kansas City and Portland and anywhere else I've seen people advocate for.
