I don't think I was cocky before the series started. At least I don't recall it.
I qualified my expectation of them winning due to Boston's ability to prevent them from getting through the neutral zone with speed. I think I also expressed my concerns about Freddy and Ron's fatigue issues pretty regularly. Both of those things have turned out badly for the Leafs. That's why I'm feeling really down on their chances.
Throw in Rielly blowing chunks and the big three not doing much of anything ... I'll be happy if they aren't swept.
