Well, I suppose come trade-deadline if CMac knows he can't re-sign Toews, he could look at a move involving him that could potentially fix the 2C longer term. It would suck for Toews to be the loser of musical chairs in this dance of LD, but somebody's eventually going to get yeeted in order to keep Rants and some semblance of depth.
Another team that may have a lot of centers on their hands is Columbus. Especially if Laine is serious about wanting to be a C. He saw what Tage Thompson was doing and made the switch a couple of games before he got injured at the end of the season. If Babcock keeps him as a C, they've got like 6 dudes that can play C (Roslovic, Jenner, Kuraly, Texier, Fantilli, Johnson, Foudy and potentially Laine). Just not sure if any of them would be what we want and if they are, would they be available. They seem to be short on quality LD (Severson, Blankenburg, and Berni) as well so if we wanted one of their C's maybe a fit could be made.
