Having speed at the linebacker position for the Raiders while Al Davis was still around was important. With the corners locked in man defense, the linebackers were often needed to drop into coverage or track down a running back in the open field.
In 2006, the top two linebackers in the 40-yard dash both became Raiders - Jon Alston (4.40) and Thomas Howard (4.42). Howard became a good starter for the Raiders and Alston was a valuable special teams contributor.
Here are the top athletic performances by Linebackers in the 2013 NFL scouting combine:
