As a long-suffering Leafs fan, their 3rd period game 7 collapse against Boston 3 years ago was pretty rough. They hadn't been in the playoffs in a decade, and they were up 4-1 in the 3rd and ended up losing. But take away the context of the playoffs and just for an individual game, the worst was a game against the Blues about 16 years ago or so. I can remember coming home and turning on the Leafs game, the 3rd period had just started and the Leafs were up 4-0. Tie Domi scores to make it 5-0, and the announcers say that it's his second goal of the night! Wow, I say to myself, I'm definitely gonna watch the rest of this game even though the result is a foregone conclusion, because I want to see if my man Domi can get the hat trick and there are few things in the game cooler than when a tough guy gets one of those. Well, I proceed to watch the Leafs squander their lead and St Louis tied it up in the last minute. Then they scored in the first minute of OT. So the Leafs were up 5-0 in the 3rd period and ended up losing 6-5 in OT.....it's really, really hard being a fan of that team let me tell you.
