I share your disclaimer.
While Center may be least physically demanding of the OL spots, it is more physically demanding on teams facing 3-4 defenses with big NTs. It is also, as you note, the most mentally demanding of the OL positions.
It seems to me, great teams (particularly those with some long-term success) tend to be anchored by great centers. And Center isn't the kind of job you typically want to give to a rookie. That leads me to believe that it is quite important to get a very good center established and keep him there. So, while I don't think they will rush him into the job, I think Wood finds his way to center and stays there. Guards can be filled with FAs, rookies, aging vets, etc. But I think you want your Center to be there game in, game out and year in, year out.
Just IMO, of course.
