Part of development is learning technique. Part is physical development. Part is mental development, particularly understanding everyone's assignments. And part is learning each other so well you "know" what everyone will do in a particular situation (both scripted and unscripted). OL in particular need all four. I assume the physical and technique parts are continuing; they are both a long term journey, not a destination. The mental development has made steady progress. I saw few missed assignments against Stanford; a contrast to early season. When a back up has to come in, you generally lose a little in the physical and/or technique areas (that is why they are a back up). Since they have all been a part of the same group, however, the mental and mind reading aspect should see little drop off at this point in the season. We will miss Kingston, but I don't expect a huge drop off.
