Not "walk away point." But you have to make a decision if you're going to pay him, trade him, or lose him to free agency.
My point (and I mentioned this in another thread) is if his contract has an AAV that starts with a 7. And I would hate to lose him for nothing.
The point of this exercise was to answer the question "why are we talking about trading Jake DeBrusk"? I love the guy and want to see him in Boston long-term. And I don't think my contract expectations for him are unrealistic.
He's just closer to a Marco Sturm level of impact to me than he is a... I don't know. Brad Marchand. If he's looking for $7M+/yr on the open market, I'd rather move him and let that team's fan base argue whether or not he's worth the money year-after-year.
