My best answer would be a crew chief that demands performance and knows how to get the best out of his car and driver each week. Also he would be half psychologist to relate to team members( actually no different than a coach) when he does that he gets better performance and results each week. Lastly he has a system for the way they do things, a system each one understands and buys into. That my friends is the formula for success as I see it.( yes I am in the coaching field myself).
Alabama needs you!
