What a **** poor deal for Columbus. Bozak is not an improvement over Wennberg, and at best a marginal one over Dubinsky, so he would be redundant in their system. Heck, they even have Jenner, looking at a bounce back year in 17-18, and Dubois, who has massive potential (albeit questionable as a C). That is not something they should be trading Murray for.
A neutral counter-proposal, assuming that Columbus traded from their blue line to acquire help at center...
Nazem Kadri
Connor Carrick
for
David Savard
Tyler Motte
With both teams acquiring something for the position in which they are weak at, they end up with another position looking relatively thin. That's why Motte and Carrick are there - they are somewhat viable options for their respective teams' bottom lines or pairings. Kadri and Savard are pretty equal in value, hence why I didn't bother to add picks to either side of the equation.
