The only place we have NOT shown improvement over last year, which in itself was a season with different variables so not really a comparable, is defensively, and there shouldn't be expectations of great improvements there over the course of a year in which our defense (AND centers AND goalies) got younger and less experienced, and in which we encountered significantly more injuries.
By efforts like last night, you mean dominating efforts for 35 minutes out of a 60 minute game?
Or by that, did you mean scoring only 1 goal? Missing 3 open nets? Those don't sound like the characteristics of one of the best scoring teams in the league on a regular basis.
Funny how a team that's "not very good" is in reality, pretty good, and about exactly where we should have been expected to be.
Perhaps people need to go watch some games from around the league and realize that even cup contenders are embarrassed on occasion, have slumps and peaks throughout the season and throughout games, like all teams. Then they can come back to the Leafs and realize that a close 1-goal game is not reason to scream the end of the world.
In fact, three 1-goal games, two of which ended in OT, facing some of the worst puck-luck we've had all season, after a long break and one of the best runs in hockey prior to it, is never a reason to panic, especially when we will potentially have a full line-up next game for I believe the first time this season.
