Realized this was actually worth exploring.
3C in one system means an entirely different thing in another system, and with a guy like Ruff as coach it could even change year to year. If you're going with the most basic definition of 3C being a checking, shutdown center then no there's really no one better than Faksa, including Eakin, who fits 3C. The way Ruff used Eakin last year and most of this year, long term Faksa fits that role better if he develops properly.
Shore would fit 3C potentially better on a team with 3 offensive lines. He's a good defensive center. Most NCAA guys do have a strong two-way game, but he's also got some Ribeiro in him ... I.E. slow the game down and pick people apart. Long term that might not exactly mesh with this team.
Honestly, Eakin's currently former line with Roussel and Garbutt are more of a traditional energy line than a shutdown line. In the future, minus Garbutt and add in a more offensive RW, that could be a third scoring/energy line. You could go more traditional checking line with Faksa on the 4th.
Probably not the start of 2015, but maybe 2016 if Seguin ultimately proves to be better at wing ...
