It looked like Corvo was the guy sitting, but I'm not sure.
It could be one of a few things:
(a) he had a mild injury or equipment problem
(b) he was being benched a shift or two for taking that hooking penalty
(c) Schubert is a larger and more physical presence in his own zone, and the Habs were pressing
(d) the Sens are showcasing Schubert
I concur. There's no way the Sens are showcasing Schubert. His value to the team is exponentially higher than your average fourth line grinder. As a utility player he has a great future with this team.
i doubt anyone is getting traded to edmonton. The sens only have seven defenceman, and buffalo showed last year how important it is to have some spares. If anything, the scout was there for the habs d-men, with them sliding quickly out of playoff position and having so many ufa's back there, souray included.
Schubert has been getting minutes on D in tight situations or on some penalty kills. This is either because they don't trust Corvo or they want to get Schubert some minutes on D because he hasn't played a full game on D for a while.
