Frankly, Ostapchuk is going to be a good 4th line checking center but doesn't have much upside to be more than that, maybe as valuable as a Kastelic in his prime.
Gregor was a free wallet and decent depth player but basically we paid a 2nd and a 4th line Center for Zetterlund and a 4th round pick
That seems like a very good trade to me. I am very encouraged by Steve Staios, he seems to have the creativity we need to become more competitive. Since Dorion messed up the 2nd part of the rebuild, we really needed a guy that would find all kind of ways to improve the team and we might have that guy in Staios. Amadio signing is a bit meh and the Perron signing didn't work out so far but there was a lot of bad luck attached to it. The Chychrun-Jensen looks really bad on paper but the loss in value falls on Dorion's shoulders no doubt.
