I think part of it falls on Chaney. His background is the very same type of offense. Heavy pass, and very little running game (at Purdue). I do think we need to put Neal in more and let him try to simply outrace the defenders to the edge, and only cut back when there is a good lane to do so. That's all Rainey and Demps did today, and it worked well enough to move the chains most of the day.
Having said that, I don't know that Heistand will stay beyond this year if the O-line struggles to run the rest of the year. It is his position that is not getting the job done, despite considerable size and athleticism at his disposal.
There must at least be some visible improvement occur between now and the end of the season, or I honestly expect to see Coach Dooley make a staff change to address the problem.
