I dont disagree, but one thing you and many others seem to forget is the coaching.
dak doesnt make game plans or design the plays, or call the plays , or decide who is playing or what position they will play etc etc etc.
Dak doesnt handle heavy pressure well, so putting steele in a new position, and mcgovern in at LT, and keeping lael at rt , were not good decisions.
playing elliot hurt, over pollard, not good decision.
When KC got pressure early Dallas didnt go heavy run offense, which aikman pointed out they should have, again not good decisions.
I think it is not so much the OL that is bad, but the play/ blocking designs that allow guys to come in free , way too often.
elliot tackled in backfield by coming in free, next play dak is strip sacked by guy coming in free ! lol it is really amusing to me, and I see it with
other teams as well.
It all starts with good coaching, not the qb.
