To answer this I am going to go back to 1954. The New York Giants had a player who was extremely smart. So smart that while he was still playing for them, they made him their Defensive Coordinator. Not DB Coach, LB Coach, or DL Coach. He was made the DC. His name, as I am sure you have guessed is Tom Landry.
He was a DC for 5 years when Clint Murchison signed him to be the first Head Coach of the Dallas Cowboys. He was raw, virtually unproven, and brilliant. There was a time when his teams struggled to grasp his systems.
In 1965 he had a compiled coaching resume of 25-53-4. Fans and the media gave up on him. Some players did too. They started clamoring for him to be fired. To move on. Had I been an involved fan like I am now, I might have too. I am 100% sure that most of the fans on this forum would hate his guts and want him gone.
Tex Schramm, the man I consider to be the best GM in History, gave him a 10 year contract extension. What the hell was Tex doing? Couldn't he see the man couldn't coach? Couldn't he see that teams were on to his plays?
I am what you might call a Football Historian. I love the History of the game. Did you know that many consider Vince Lombardi to be the greatest Head Coach to ever stride the sidelines? That the Super Bowl trophy is named after him because his team won the first 2 of them? Okay, I am pretty sure you do know those things. Did you know that for most of his time coaching his Offense was predictable? I'm guessing you didn't. He had a Fullback named Jim Taylor who he ran a lot like Marion Barber. Like he took it personal.
Jim Taylor was Lombardi's "Bread and Butter." Teams knew he was going to get the ball and which direction he was going to run. The problem was stopping him. Sometimes they did. Sometimes they didn't. When they couldn't the chains moved and the Packers would score. You talk about predictability as if it is a crutch. If there is performance tied to that predictability it can be devastating. Green Bay is called Titletown for a reason.
I'm sure you are incredulously asking what this has to do with Jason Garrett? I did not dare just compare Jason Garrett to two Hall of Fame coaches. I did. The common factor between the 3? Football brilliance.
Back when Jason Garrett was the 3rd string QB here Jimmy Johnson (maybe you've heard of him) realized how brilliant Jason Garrett was and effectively assigned him to be the QB Coach for Troy Aikman. While he was still playing. After he left here and went to the Giants I saw an article where they talked about Jason Garrett understanding the Offensive system even better than the coaches and they often turned to him in meetings.
"Those who cannot remember the past are condemned to repeat it." --George Santayana, 1905 in his book Flux and Constancy in Human Nature.
If you want to turn a blind eye to the fact that Miami did not want to lose Jason Garrett, be my guest. If you wish to turn a blind eye to the fact that 4 other NFL teams have put him on the radar as a Head Coach, be my guest. If you choose to ignore the commentary of Troy Aikman, Michael Irvin, Darren Woodson, Montrae Holland and even Terrell Owens on Garrett's knowledge of the game, be my guest. If you choose to ignore the fact that Jerry Jones made him the highest paid OC in the NFL in the hopes of him one day taking over as Head Coach, be my guest.
But don't ever for one minute in your life, waste your time thinking I am going to hop on board your Jason Garrett sucks bandwagon or agree with you about him. Don't waste your time. Stop asking me. Or learn the game and its History. I simply do not agree with the howling masses of fans and media who think this guy got figured out and it will doom this team. I simply don't agree. History has a way of repeating itself.
