Jerry finds he has no better options unless he steps back and gives up more power.
'Better options' is relative to the person considering them. Jerry Jones hired Jimmy Johnson and Bill Parcells. Jones hired Barry Switzer, Chan Gailey, Dave Campo, Wade Phillips, Jason Garrett and Mike McCarthy.
In both circumstances, Jones did not do an extensive coaching search. His gut told him to hire his old college teammate, who was successful at the college level. His gut told him a two-time winning Super Bowl head coach would secure him the best (east/west) stadium he imagined.
His gut told him another college teammate, who was also successful at the college level, would be his '500 coaches' solution. His gut told him an offensive coordinator would re-kindle his team's offensive prowess--only to give up on his choice two years later.
His gut did not warn him his choice was not respected by his players as a head coach. They even de-pantsed the man in practice.
His gut told him to hire an offensive minded prodigy (his gut) before hiring a defensive minded mainstay with a so-so head coaching record. His gut said he already had the next Tom Landry. A decade later, his gut told him he could not continue waiting on Tom Landry type results.
His gut said an out-of-work ex-Super Bowl winning head coach would be an easy hire. Four years later, his gut said do not re-sign his head coach before the final contract season.
Jones has plenty of options available to him. His track record suggests he minimizes his available options to less than a handful. In doing so, his actual hires meet the conditions he desires. This is why his better options more often do not coincide with the better options observers see-and-believe he should obtain.
Jerry finally realizes that his inactivity in free agency and dragging his feet on contracts hamstrung the offense without a RB, without a second playmaker, and hamstrung the defense without interior defensive help and depth at CB and LB.
Jones re-signed Ezekiel Elliott, two seasons after he released him. Jones knows exactly what he is doing because he believes he makes sound player acquisition judgments. That is what
he realizes.
Jerry realizes that the OL wasn’t ready to compete with 2 rookie starters in new positions and that the defense wasn’t ready or properly manned for the new DC, especially after being decimated by injuries.
This hypothesis is totally dependent upon how the offensive line improves or regresses now-and-through the end of the team's season.
How many games can you really expect to win with the offense scoring 6 TDs over 4.5 games without your starting QB to date? The two wins show that McCarthy is still a good coach who emphasizes complimentary football.
Great question. Unfortunately, the general manager believes his specific head coaching choices should be successful with the rosters he provides them--which he overrates moreso than outside observers judge.
