It definitely failed - market shares and grassroot interest is not present in the US....
Kids there would rather - play football, basketball, baseball than hockey....I've always said that hockey is a fringe sport in the US. NASCAR, Golf, March Madness and College football are all bigger than hockey in total revenue. Shit even the World Poker Tour gets a better tv deal than hockey.
Most Americans could give a rats ass about hockey...and if this strike persists, I'm guessing some Canadians might lose interest. But not Leaf fans....but thats another ball of wax.
Plus the players better get supplemental insurance - why should the owners be liable for a injured product? You get hurt - the existing contract should be null and void - besides dont most contracts have a "jughead"clause?
