Yes, the guard did change last year, but the 'changing' was underwhelming. Out were Cole and Zadorov; 'in' were Desharnais and Forbort. They brought back Myers and Soucy. And Friedman was supposed to be the 'swing' guy.
Fast forward, Desharnais and Friedman are gone; and Forbort and even Soucy may join them. The only 'constants' are Hughes and Hronek, and the latter has missed two months with a shoulder issue.
