Wild fan here. I thought that you guys played a solid game, and dominated in parts, like in the 4 v4 minutes. Your defensive play, and especially goaltending, was vg. MN prevailed towards the end of the game, but that's what you get when you are playing at home against an opponent who played the day before, and had to travel.
Your PP will get untracked, with the talent you have. I don't know what your PK is like normally, but it was vg yesterday.
3 v 3... eh, it's a weird animal. I was pretty shocked at how fast the 35 yo, post hip surgery Spurgeon skated to negate the chance, but in general, you take the point every time considering the circumstances, right?
I do think that Berube will be good for you. He will make you a tougher team that will play D. As long as you can score on the PP, then you will be able be effective.
For reference, I have watched the Leafs play for a long time. Tim Horton and Bobby Baun were two of my favorite players as a kid. Still remember Keon, Sittler and that crowd, Vaive, Clark, and the Gilmour and Sundin years.
