You know what's awesome? You're expecting a sense of humour from a group that you're nebulously defining through labeling, gross generalization, stereotyping, and discrimination. You're all a credit to humanity for forming the church of anti-"Diazirites".
You know who else helped in those three wins? Subban, Plekanec, Gionta, Gorges, Markov, Emelin, Briere, Bourque, Prust, Gallagher, Desharnais, Bouillon, Beaulieu, and Murray - all of whom played more than Weise. And then there's White, who played less but brought more. But I wouldn't read too much into games against 2 non-playoff opponents, and another that is decimated by injuries to the point of possibly falling out of a competitive run in the West. Of course that's going to be the inclination, though.
As for a "happy Weise", he was happy at one point in Vancouver, too. Then he (mistakenly) thought he deserved more than a 4th line role. We'll see how long he stays happy down on Montreal's 4th line, because he isn't moving up as we get healthier. I certainly don't think he "sparked" White anymore than watching from the sidelines was already spurring him on as the team went on a 5-7-3 skid during the month he was out. But if it fits the agenda of the church, all shall believe.
