The offensive line is the big problem. Too many changes: Replacing Whit, Allen, Edwards, Sheldon, & Anchrum has devastated the offensive line. They can't protect or run block worth a darn right now. You know you are in trouble when you see Bobby Evans lining up.
McVay/Coen are going to need to cook something up and fast to offset this deficiency which will be quite difficult. But ditching the longer developing pass route and rolling the QB would be a good start. Not sure what to do about the running game but running guys into the line isn't working at all.
