It makes a lot more sense to move Kerfoot than Holl right now TBH.
How many forwards have looked impressive in camp this year? Kerfoot is solid too but I don't think we are losing major quality going from him to Anderson, Malgin, or some other prospect like we would going from Holl to Mete or a UFA. That doesn't include the various defensive injuries we have right now. Muzzin and Gio should be getting rest days as well, and who knows about Sandin's health. We will need at least 7 good defensemen.
Kerfoot should have a pretty good market.
