While Carrol could help for sure, it seems to me that a lot of the issues with the run game are the 3IOL spots - a lot of penetration is coming up the middle and doesn't involve the OTs. The rotation has been so deep with so many guys playing that I don't really have a solid idea of which of the 3 it is. i.e. against UGA, with the first 5 guys (Dewberry, brailsford and VDM inside) , we seemed to be running pretty well and then started changing all the things up, and I think the run game started not working all that well. Could have been UGA adjustments, or could have been the different lineups.
I don't love the idea of playing this deep with this many variations in the lineup b/c a lot of OL success is chemistry, especially with combo/duo type blocks, and having 5 guys rotate through 2 spots, with some playing at each OG spot, makes it much harder to develop that chemistry and the 'feel' for working together.
