2014 Offensive Line

Outside of the obvious recruiting effects, how does the departure of Grimes affect the crop of current/incoming players projected to play offensive line on next year's team? Will seniority hold any type of advantage? How heavily will the Spring and Summer evaluation periods (as opposed to film review of play throughout the 2013 season) be in determining the starting five for 2014? I know a huge part of answering these and other related questions depends on the philosophies of the coach we eventually hire. Still, I'm curious what French and others have to share about such musings.
