He is regarded as one of the greatest crew chiefs in NASCAR history, guiding Johnson to a record five-straight championships and 53 victories since the two were paired in 2002. Knaus is not credited with two other victories Johnson earned while Knaus was suspended, including the 2006 Daytona 500.
Knaus had been kicked out of SpeedWeeks by NASCAR in 2006 for alterations found on the car following Johnson's qualifying lap.
Despite this controversial start to the season — which comes after Johnson finished a career-worst sixth in the Sprint Cup standings last season — Knaus has been determined to keep Johnson moving toward the front of the field.
He guided Johnson to a fourth-place finish at Phoenix and a second-place finish at Las Vegas. The finishes have boosted Johnson from 43rd in the standings following Daytona to 23rd.
