knaus stepping down as crew chief for the 24 at the end of the year. will remain with hendrick in a vice president role. he didn't mesh particularly well with byron, personality-wise, from what i heard on their radio at various points. knaus is a demanding and ornery guy, just like jimmie johnson - he's also used to winning. byron is a quiet kid who has been under massive pressure since day 1, known to most fans as 'driving jeff gordon's car,' and only just got his first win towards the end of this year. i think they'll move greg ives from the 88 team over to help him develop. he's worked well with bowman, who has a similar temperament.
