"If he thinks it's important, he's going to be on top of it. Period," offensive coordinator Dan Henning said. "The amazing thing is there are many, many things he thinks are important."
Attention to detail? When Sparano sought to improve the coverage units, he revised the practice schedule to extend special-teams work from eight minutes to 12.
It wasn't a casual decision.
"Everyone in this league is up against it getting their team ready to go," he said. "The use of four minutes and how we use it, the use of two minutes and how we use it ... I'm a stickler for that."
Newly signed safety Gibril Wilson has seen the value of that approach. He won a Super Bowl in 2007 under New York Giants coach Tom Coughlin, a veritable drill sergeant. Wilson won only five games last season with the aimless Oakland Raiders.
"The Raiders, that's why they're where they're at and the Miami Dolphins are where we're at," Wilson said. "It's huge going from a place that's structured to a place that's not and coming back to a place that's structured."
To maintain that structure, Sparano keeps an ever-growing pile of information in the one place he knows it will be safe - his head.
After a recent media briefing, Sparano didn't hesitate when asked if he knew what his team would be doing at 9:28 a.m. three days later, when Miami would be preparing for its exhibition opener against Jacksonville on Monday at Land Shark Stadium.
