I think Savard gets first rounder pick value at the TDL, but not so much now.
They will pay that value for a D to put on defensive missions (PK, D Zone faceoffs), where his physicality and shot blocking can be put to best use. He will likely play 3rd pairing otherwise. Seems like a calming presence that pushes you to work harder through hard work and sacrifice - everything a team needs in the playoffs.
I think Mtl keeps him till at least the TDL, and only if they feel the D are ready to be steady without him.
