All thanks to some remarkably shitty owners. RIP Atlanta Thrashers, slowly and gruesomely murdered by Don Wadell, Patrik Stefan's flop (not this one), Steve Belkin, Dany Heatley's driving, the stupidest lockout in the history of sports, Kari Lehtonen's groin, 400 draft picks for 18 games of Keith Tkachuk, Ilya Kovalchuk's insane contract demands, Joe Johnson's dumb contract and the Atlanta Fecking Spirit Group.
Of course we are talking about Bettman's expansion-era trainwreck of a league here. It sure won't be long before one of the other half dozen floundering franchises takes a long hard look at an empty Philips Arena smack dab in the middle of a city with a population of over five million and decides to become the next
Of course shitty owners tend to migrate to new cities along with their ruined teams, unfortunately.
