The opposite side of that 'guarantee' argument is annointing him when he hasn't accomplished anything either. Every coach is a question mark. Some turn out well, some don't. But somehow Garrett is beyond question.
Garrett was always considered a smart guy who got by with intelligence over physical ability. Many thought he'd be make a good coach and it runs in the family too.
They obviously didn't want him so badly that they'd do anything to keep him - including promoting him. And they had first-hand knowledge of his abilities at that point and knew what kind of coach he was better than anyone.
You can throw out all of the games Romo was injured and Garrett still struggled to get the most out of the talent he had while Sparano was able to maximize what he had in Miami. That's not theory, that's fact. Not to mention the criticism leveled against Garrett for even having Brad Johnson here as his backup QB which certainly cost this team.
Garrett was riding a huge wave of success in '07, there's no denying that. But when the guy had to do it himself, he struggled, and his shine suffered as a result.
How many interviews did Sherman Lewis get? And where is he now? Lots of people get interviews for jobs they never get or aren't qualified for. Some even get the job. Funny how even the Rams and Lions wouldn't hire him given how bad they were in '08. That's the bottom of the barrel saying "no thanks".
And yet, when all is said and done, he's still here in Dallas, trying to fix his struggles of 2008.
As a fan, I hope he succeeds, but that's far from the certainty some would like to believe.
