It was the defense that really tanked in Wade's final 1/2 season. That defense had plenty of talent. It was their mindset that was the problem, not talent.
You said that Garret was bad years ago and now you have a need to try to prove that you were right despite mounds of evidence to the contrary.
Again, referencing Garrett as an OC is just getting off topic from the question of his ability as a Head Coach. Linehan works for Garrett and had to have approval from Garrett to be a run heavy offense.
Wade was a good 'ol boy. He threw a jazzed up barbeque on his ranch, but allowed a lazy attitude fester in the hope of stopping injury. Camp Marshmellow didn't forge a new season, by vainly tried to hold onto the past with his own thoughts mixed with his growing old players.
He was pulled in season, and replaced by Jason Garrett. Now, there is nothing Jason could have done at that point, to have saved face to many spoiled fans - who merely would accept only a picture of increases in Lombardis. That points to a low ebb in fans, not an inept arrival of Jason Garrett.
Jerry knew what it took for growth and a potential dynasty franchise, and invested in that same Jason Garrett.
Jason had great leadership skills, and knew the core ingredients of a NFL type of integrity and sense of morales. Jason sought out top quality, but also at the same time, leadership and commitment to work and mix it up on the field. Instead of coaches that slapped him on the back, Jason invested in quality coaches that could hold the players to standards and be a key ingredient in a long termed Championship building. This is a great blend of coaches, with both Coordinators as intense and empowered as were Norv Turner and Dave Wannstedt, under Jimmy Johnson.
Jason has the ability to build just as strong a team as did Jimmy Johnson, but with a better team orientation and commitment as well. Jason heads a great leadership group that are his coaching staff.
Both Jimmy and Jason required time to build a truely competitive team. But the major difference now, is that Jason doesn't also bite off heads and pee down the nubs to get results from his players. But he does have an empowered Jerry Jones to assist him in getting players. I'm thinking that the signing of Collins this off season, says a ton as to directions now.
