Agreed. The one goal Samsonov allowed was a bit weak but he was hardly the cause of the loss and he stopped a clear breakaway in the third. Bob was good, but the Leafs also hit like 4 posts and 2 crossbars so... also very lucky.
The truth is that the Leafs were dominating this game and then gave it away with lackadaisical plays that cost them their momentum and the game. Often they simply REFUSE to make the simple play and chip a puck out of their zone for fear of losing possession. I don't know why, because they just lose it in a worse position 50% of the time by holding onto it.
