N/S Article - what makes a good offensive coordinator?

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
