Why yes, I have been watching the entire series.
It's a bit historical, but it's not really as dramatic as it would seem on the surface. The Bruins won 3 game 7's on their way to the cup two years ago. And the Leafs were eventually caught by the one mistake they couldn't shake all series: The total inability to clear the goddamned puck out of their end when it mattered.
Boston spent most of the series simply expecting things to go their way (on paper they were by far the better team). The Leafs just wound up making the same mistake at the worst possible time.
Other than that, they learned a hell of a lot for a bunch of young guys that no one was expecting much of. Maybe if they were an older gang, that'd be harder loss to take, but the Leafs are the youngest team in the NHL and they've really shown that they're all willing to learn and work together. So I think better things are on the way.
