This is not a very sexy move, but Colorado is in desperate need of 4C help.
The defacto option on the roster is Chris Wagner. Last year was Fredrik Olofsson (bad defensively, rancid on faceoffs) followed by Yakov Trenin at the deadline... aka a winger forced to play center. The year before that was a combination of Jayson Megna, Ben Meyers, and Lucas Sedlak. In case you couldn't tell, the Avalanche have bungled the position since losing Darren Helm.
