I can see where Bettman is coming from. In Calgary the deal is stalled because the city wants some sort of return on their investment, which the Flames just can't afford to do.
Meanwhile in Ottawa, they're open for business, with city administration making statements like:
'Any liability the city agrees to take on would also "need to be secured by assets or a mechanism to recover the costs from the benefiting area," staff wrote.'

It's pretty clear who's negotiating in good faith and who isn't.
