He's one they should've found a way to resign. Good on face offs and did a lot of the dirty work. Not to mention he's a solid playoff performer.
They wanted to. Wasn't money with him. He left after AV told him they wanted him back in a similar role. He left to pursue a better opportunity.
Expendable. You can't pay role players who get 10 or less goals a year, close to 2 million a year. You will not be able to sign your better players. Another example of why signing Glass was so f'n stupid.
