I would split a few hairs with the author.  I don't see RB depth as a weakness, more RB experience.  We have at least 3 if not 4 very capable guys in my opinion, unfortunately at least half have never taken a snap in college.  That said, RB is one position where a frosh can make a big impact.  I believe you are more apt to see a standout freshman RB than a standout freshman OLine man.
I don't think the success of the offensive line is dependent upon Herbig.  He has proved he can play.  I believe the key will be left tackle.  If we can line up a left tackle who can block an edge rusher, it will be a major boost to our offense.
I don't see safety experience as a big issue.  The returners have proven they can play.  I am far more concerned about whether we can put two guys on the field who can take some pressure off of Philips.  We are one injury away from some major issues on the defensive line. 
Lastly, I think Special Teams should be part of write ups.  Mac provided us with a major threat on returns, often causing opponents to kick away from him, often giving us pretty good field position.  Field Goal wise we also had probably the best kicker we have ever had, and our punting was also pretty darn good.  All told, special teams were a major contributor last year, can they come close that level this year?
