Don't read more into blocking schemes than what they are. That's what's so perplexing about whatever the hell Deleone has done to this offense. You can either count to six, or you can't, and you either move as a unit together, or you have individual movements based on position and play call. Deleone has changed the offensive lineman stances, and movement patterns signficantly, and at times, I can't for the life of me, figure out how the offense (and I mean entire offense - not just the 5 OL) is determining who to block prior to snap and what to key on and look for. THey could be standing in front of fence, and fail to get their hands on it at times (and that means everybody - not just the OL)
I would bet that the linemen that have had both systems would be relieved, and happy to go back to the stances and moves they were taught by Foley - for the simple reason, that they know that it worked when they did that. Simple psychology.
