They have 'clock management specialists' in other sports for head coaches that are great at everything except in-game clock management, since they're juggling multiple personnel decisions and generally focused on directing the team than dealing with the clock.
Doesn't really apply for nascar a 'late-race strategy specialist' is literally the crew chiefs job as the laps wind down, factor in all the input and feedback. The driver has to trust the crew chief and the crew chief has to have the confidence to make the call. I can't remember Chad deferring to Jimmie many times, if ever. There's room for different approaches I guess, but primarily in my opinion, the driver should be focused on visualizing how he's going to win the race on track, not having to worry about making the right pit call in the final sequence.
