I was also thinking about Sarrazin and Bryce Tirabassi. They drove for the Subaru squad towards the end of its tenure in the WRC. I think that Sarrazin is a bit wasted in IRC and Tirabassi did well to win the JWRC in 2003. I am unsure to this day why neither got full time drives. I think that Urmo Aava could also be added to this category of "could have been" WRC drivers.
