"At the very least, he could be another experienced body at camp, play some preseason games, and leave if things don't fit. However, bringing him in on a risk-free deal and seeing him flourish could benefit the Leafs throughout the season or potentially even beyond.
He has good years left ahead of him, assuming he can stay healthy, so a PTO could turn into a one-year �show us' deal that could, in turn, become a longer-term deal if Labanc fits in well.
There's virtually no risk if things don't work out, but there's potentially all the reward for the Leafs if it goes well."
