I appreciate the contributions here from Habs fans, and it is refreshing to read supportive posts about what he brings to the ice. Being a Montrealer, I have had ample opportunity to see White's tenure with the Canadiens. He absolutely represents an upgrade over Rinaldo in that he can PK and can take defensive-zone faceoffs, and an upgrade over Hall in the speed department.
I am not convinced, however, that White has turned the page on taking stupid penalties or on layout out suspension-worthy hits. It's the nature of the fringe-NHLer energy guy; he has to play on the edge to be noticed enough to stay in the line-up.
If the plan is to keep Laughton in the AHL unless he blows away the coaches during camp, a 4th line centred by White and without Rinaldo will be a step forward from the quality vacuum this line represented last season.
