MOORE, Okla. - The tornado that struck an Oklahoma City suburb this week may have created $2 billion or more in damage as it tore through as many as 13,000 homes, multiple schools and a hospital, officials said Wednesday as they gave the first detailed account of the devastation.

The physical destruction was staggering.

"The tornado that we're talking about is the 1 or 2 percent tornado," Oklahoma Department of Emergency Management Director Albert Ashwood said of the twister, which measured a top-of-the-scale EF5 with winds of at least 200 mph. "This is the anomaly that flattens everything to the ground."

Urlacher was the face of the Bears, and he ranks among the best middle linebackers to suit up for a franchise with an impressive list that includes Hall of Famers Bill George, Dick Butkus and Mike Singletary.
