If ZAR can turn his PTO into a deal with the Leafs, at 6'0 but 205 pounds, he would add a much needed physical presence to the Leafs' bottom six, similar to that of Nicolas Aube-Kubel.
Both are wrecking balls and hit everything in sight, but are also able to kill penalties and be defensively responsible. Having both of them on the fourth line would be a complete change of identity for the Leafs' bottom six, something that is much needed, particularly come playoff time.
