You start to wonder how important Newey is.
How much of a coincidence is it that the RB can't progress and Newey's not working on the car anymore.
Obiously he doesn't design the car by himself, so actual input is difficult to quantify, but race performance is easier to quantify, and the difference is there, coincidence or not...
We'll know in ~1,5 years how good AMR is then
