Depending on the Mack diagnoses, I think we have to call up Maltsev at least, and I'd call up Kaut too. May as well see what these guys can do down the stretch in nothing games so we know if they can be options for the POs. Scratch LOC and Helm/NAB to light a fire under their butts.
Nuke - Kadri - Rantanen
Lehkonen - Newhook - Burakovsky
Cogliano - Maltsev - JTC
Helm - Sturm - Kaut
As has been pointed out, someone other than Cogliano (Copp, Rakell, etc) would be looking a lot better right about now.
