Jimmie Johnson won his record-tying seventh NASCAR championship Sunday with a familiar figure by his side _ crew chief Chad Knaus. The two have been together for each of Johnson's titles in Hendrick Motorsports' No. 48 Chevy.
Knaus, who is one title shy of tying Dale Inman's NASCAR record of eight titles for a crew chief, talked about this championship and what makes Johnson so special at what he does.
