Our problem seems to be OL recruiting more than OL coaching. We’ve had a lot of great linemen but rarely more than one at a time. Our guys do typically develop a lot between seasons and we are really good in pass protection ... just not good at run blocking. I think that is due more to scheme than anything else.
i think this is a great point and one that really came to focus this past year when there was an absence of upper classmen in the interior offensive line.
another point is the offensive line requires more coordination than any other unit on the field. individual talent can be identified, individual talent can be developed, but run scheme, pass protection as a unit, communication within the group, and getting those five guys to work together is critical.
you can excel in those first two areas as offensive line coach, but if you can't get the group to work together things break down quickly.
similar to discussion on cumbie developing quarterback talent. that skill set is apart from offensive scheme design and play calling.
