Yes I do agree with you they were "hopeful" if we're talking early season predictions, you are correct, but when Kane signed, the team was in a really good spot and we were half way through the season already. I feel like him tempering expectations is just excuses for this historic collapse at this point. There's no way the post-TDL collapse was the expectations from Kane, Yzerman, Lalonde and the rest of the team. I would freaking hope they felt good about their chances, or else the "loser attitude" that some have mentioned would be concerning and probably one of the reasons for what happened.
In the grand scheme of things, this collapse doesn't matter one bit but for the players, the coaches and Kane, there's no way they are ok with the recent results. For us, the fans, it's frustrating but we'll get over it as the team is clearly improving from year to year. Let's hope they win the last 2!
