I don't know about anyone else, but I'm having a hard time dealing with the cognitive dissonance over the ideas that we won't get anything for Bozak or Allen because no one has cap space, and that we're going to lose Pietrangelo this offseason because a bunch of teams will clear cap space if they need to in order to sign him.
Bozak and Allen absolutely both have positive value. Both could improve the roster of many, many teams in the league. Both are slightly overpaid for their appropriate role. We will not have to pay anything to get rid of either of them, let alone sacrifice Dunn to make a deal happen. While either may have returned a 2nd-3rd or a good prospect, we'll probably only be able to get a 3rd-4th or a decent prospect unless we take back money in an NHL contract or modest retention, but that's what happens when the cap goes flat. If Army moves Dunn, it will be because he believes that Perunovich is ready to step into the same role and he can get a premium for Dunn, not as a throw in to dump salary.
