An interesting question. Is the issue pocket depth or width? They say C and OG are responsible for creating pocket depth and OT for width. They only took one OT on the draft. Many broken plays last year seemed to be due to a failure of communication of blocking responsabilities after OC Lindsey was injured. But in most pressures, idk if the issue was mostly the responsability of interior or exterior OL.
