On the winning goal, I agree with the others whom pointed out that Caufield made an ill-advised pinch. However, puck possession in the 3-3 is arguably the most important thing, and so I think that Matheson also deserves a bit of blame (not as much) for putting himself into a situation where he was bound to lose the puck by ending up on a 3on1 caught up ice where HE is the one and only defenseman out there. I still like Matheson and the Habs are a better team with him while they have so many young defence, but obviously his biggest fault is his penchant for taking unnecessary risks that too often lead to goals against.
Poor decision making, by different degrees, by 2 of the 3 skaters on the ice. Caufield, at least, will learn from his mistake. Matheson should know better by now.
I only got to see half the 3rd and the overtime, but the effort was great, especially on killing off that double minor.
