Atlanta metropolitan area has over 5 million people, the entire province of Manitoba where the Thrashers would re-locate holds for comparison 1.2 million. That no-one in Atlanta cared is only a case of not knowing how to attract the fans - the soccer team NY Cosmos sold full stadiums in the 70's and entire US was not interested in soccer prior their arrival.
Maybe some of the NHL marketing guys should hook up with Vince McMahon. If this guy can build multi-billion business out of big guys acting badly in tights who knows where he could take the NHL?
Just because there are 5 million people in Atlanta doesn't mean there are 5 million hockey fans. 5 million people and they couldn't fill the arena, couldn't attract and sustain a following and couldn't make a go of it. It was a great market for the NHL to try, twice. It was a great idea to try and get Atlanta hooked on hockey, but it came up short, twice. If the league had a chance at getting that national TV deal, it needed Atlanta, but clearly that deal is as much of a pipedream as my childhood dream of getting to the NHL.
This isn't a case of "if we build it, they will come". They could very well have came, but they chose to stay home. The team sucked so people didn't go, but the NHL depends on fans since it doesn't have that huge TV deal like the NFL. If you have it, take advantage of it because there are cities out there dying for a chance at a team (Winnipeg & Quebec among others). So why should Atlanta get to have a team regardless of whether or not the support is zero, when there are cities that will sell out the rink 90% of the time and live and breathe for that team.
As for your earlier post, Calgary is the 3rd largest city in Canada at almost 1,000,000 people, metro area is well above that. It may not resonate with fans in the south but it would be a terrible for the NHL to not be in that market from a Canadian standpoint. Edmonton has a metro area roughly the same size and it would not be smart to up and leave. Better yet, I still haven't figured out if you're serious or not or why I'm taking time to respond.
