Chris Johnston is reporting this morning that the Leafs are certain to make another move before 3 p.m:
I know they’re not done. They still have at least one more move coming. I think it is likely to be a depth defenseman. I would be surprised, given the Leafs have some cap space in LTI, if the Leafs didn’t make use of it. It is pretty clear based on what we have seen so far that they’re all-in. They don’t want to leave themselves short anywhere.
With a defensive depth center (Riley Nash), a versatile top-nine winger (Nick Foligno), and goaltending depth (David Rittich) all added to the fold, the obvious target remaining is extra defensive depth.
