I mean, that guy was only the greatest linebacker in NFL history.
And it's not all that unusual to see white linebackers in the NFL. Urlacher, AJ Hawk, Clay Matthews, Jr., Mike Vrabel was very good in his prime, etc. That's off the top of my head.
Before you open your mouth wide, like you do just before you go down on your dad, you might want to see the video of Chris White on YouTube catching Trey Burton, Jeff Demps and Mike Gillisee from behind. You know, three "black" guys that have "world class" speed.
