They're trading him because they can't afford to re-sign him. How would sending Nyquist, who they also couldn't afford to re-sign, be enticing to them?
He was always going for futures. And if that's all you're going to get in return, why trade within the division?
That makes sense. It's just crazy. He is the exact type of player that Holland and Babcock were whining about for the past 4 years. The fact that he was even available was silly.
