Well London has lots of non-American football clubs, a couple of which have been quite good historically. I don't know if internationally there are the same number of sports that draw the same attention. But Boston is up there so far because- all major American sports are represented, all of the teams have had recent success, and such a large proportion of the population is emotionally invested. Is there any other city where four teams in different sports can sell 17k tickets to every game in the same season? Then again maybe we Red Sox fans need to start writing songs for every hitter like baseball fans in Japan and Korea.

Melbourne's reputation is linked to sport, given that it is able to hold so many major sporting events for a relatively small city (3 million people). The annual AFL Grand Final attracts 100,000 people to watch the game as opposed to just enjoying the surrounding hype of a Superbowl, and this is after 22 weeks of games that include 10 teams from Mebourne in a national competition of 16. The weekly hype of games means that no one can go without an allegiance or avoid discussing the matches - stories about the players or the league regularly lead the news or hit front pages of newspapers, not just the front of the sports section. There is also the Melbourne Cup, which has far greater global reach as a horse race than the Kentucky Derby, and the Australian Open tennis as well as an annual Grand Prix.

Greater London hands down. They have more football teams then they know what to do with (Arsenal, Chelsea, Tottenham, Fulham, West Ham, Watford, Milwall, QPR, etc.), rugby, ice hockey, an annual sold-out NFL game, Wimbledon, the upcoming Olympics, among others. While they may lack in popular North American sports, they more than make up for it in terms of the sports the rest of the world likes to watch.

I'm not from there, but must give credit where credit is due. How many sports and/or teams - as opposed to a dozen in one sport - allow you to qualify for this survey?

Not one but two of the major north american leagues are trying (or not) to have another team placed in the GTO area.

Maple Leafs - 2nd in (Ice) hockey champs
Argos - CFL (look it up)
Blue Jays - MLB champs twice in the early 90's
Raptors - NBA

This list of four doesn't begin to mention the legions of junior and semi-pro teams that oppurate in the Toronto area in several leagues.

If the Bills want to move there...must be the best sports town...or the best sports town with a glutton for punishment.

As a Sydney-sider I hate saying this, but Melbourne is easily the most sports-involved city I can think of.

In addition to the Melbourne Cup, the AFL domination, the Austrlian Open Tennis and the Grand Prix, Victoria also won the Sheffield Shield in cricket this year. The MCG, the heart of Australian cricket, has been voted as one of the seven wonders of the sporting world.

Also in A-league soccer Melbourne completed the treble last season after winning the Grand Final, winning the Premiership, and winning the Pre-season cup. And Victory has easily been the most successful team in the short history of the A-league so far.

I don't know enough about Melbourne. London is a good pick. But Indianapolis? Toronto???

The Boston Celtics are the greatest NBA franchise (or tied with LA), the Red Sox have a "better than fiction" history, the Bruins had Bobby Orr, the Patriots were THE football team of the last decade, there's the Boston Marathon, and 22 universities (remember Doug Flutie?), not to mention some of the fiercest high school hockey. Don't forget The Country Club in Brookline, as well as Essex (the oldest golf course in the country). The mix of working class heros and all those students makes for a magical sports town. I remember chasing baseballs that cleared the Green Monster and I remember barely seeing the court for all the smoke in the Boston Garden...
