Very much disagree with the premise
Coordinators are way down the list when blame comes around mostly bc we don’t see them
We see QB first and foremost- then HC - then either higher profile RB or WR
Beat reporters might get some answers from them, but they’re as high profile as linemen
Speaking of linemen, more and more I think that’s the beginning and end of the offensive answers- your O goes how your line goes
And very few linemen in college and doing what they’ll need to do in the pros, so fielding a good line is getting harder and harder
