I like Larry more but would not mind either.
Gus may have more upside but Larry seems to embrace the role. Larry may feel different if it was 4C if Sam moves to 3C.
As stated earlier, Asplund, Pu, Estephan and Malone could be pressing for a job in a few years.
One aspect of Pu's game that could really help is faceoffs. I believe he is near the top in the OHL. Hope this skill transfers to his pro game.
