I don't think Hendrick is all that concerned about drivers successes as long as they fit his racing model unless they don't fit. Examples are keeping Kahne for years of non producing and in turn giving him a golden parachute of a years salary and a job with another team when he cut him from the team. The other is getting rid of psycho Kyle who was a hot shoe but he didn't fit in. He has said publicly, I can't remember which driver, I know he did that for Johnson that they had a job as long as they wanted.
Rick said this about Jimmy. " I tried to sign him to a life time contract like I did Jeff. The bank told me I couldnt afford to."
