My thoughts are these:
First guys, the secret to a happy long relationship is learning how to apologize for being right.
When it come to arguing with your wife, being right isn't the thrill you might think it is. It typically earns you an all expense paid trip to the couch where you can enjoy the satisfaction of being right.
Let your wife win that 90% of the least significant arguments. That way she is more inclined to let you win the more impactful disagreements.
Never yell at her. The moment you begin yelling, she loses focus, she will stop listening to a single word, all she will remember is that you yelled.
And again, the rewards for allowing her to be right are plentiful.
As to the Cowboy's philosophy of acquiring talent, it was never their goal to quickly produce an All Pro offensive line.
As per Jason Garrett, the Cowboy's wanted to maximize value by going for the best player available. It just so happened that they turned out to be offensive linemen. Recall that both Frederick and Martin were not the players they had targeted, they were looking for specific players that were already taken.
If the best available players were D-line men then perhaps they would be the strength of the team and we would all be lamenting the need to improve the O-line.
In any case Jason explained how drafting for need reduces value and, although he is one voice of many in the room, it seems the Cowboy's have done a good job in keeping to the plan, a critical component of success.
By the way, he also mentioned that you never sacrifice the future for the present. Take note of the fact that, during Jason's tenure, the Cowboy's have never traded a high future draft pick for a player to "fill a need".
