I think you've made your opinion pretty clear...
Look, I HATED the call and felt bad for Canada after the game, but they've proven themselves to be a bunch of bitter duck*ing clowns with the way they've handled things post game. Actually, they proved to be clowns even before the game, when their coach was already blaming the officials in the pre-game press conference.
Terrible call aside, here are the facts: Canada had three leads in the 2nd half, and failed to hold a single one of them. When you blow three separate leads in the 2nd half of a semifinal game, you have yourself to blame more than anyone.
On top of that, it's not like the PK led to the game-winning goal; Canada had over 10 minutes in regulation and 30 minutes in overtime to win the game. Instead, they let up a goal with 30 seconds left in the 2nd overtime. That doesn't negate the horrible call, but they at least had a chance to come back from it...and failed.
Canada has reacted exactly I would expect in this situation - like losers. I hope they get smoked in the bronze medal game and Tancredi suffers a bad injury.
