Cause right from the horses mouth ,it's not just the car but him as well. Just accept his chassis isn't the real main problem (if the chassis is even an issue)..
I really do not get how people can't hear the words spoken by him.. it's clear as day. I'm sure blaming and wanting to believe his car is the problem between teammates but when the man himself says it, the fact that Russell is comfortable enough to say it and knows what the real issue is and the fact that Russell is pretty humble..
People just need to accept fact.
It's no big deal.. so what.. its not as if Kubica is costing them points.. hopefully his feedback will help cause man alive Stroll Siro etc.. never helped their cause this year in development..
I have my own thoughts on whether Kubica can actually help in the direction to take but doesn't matter, Williams believed he could so time will tell, if they resign him then a sign that he is providing meaningful back that Russell alone is not.. time will tell.. As will the be story for the squad this year.. very little other then results on Saturday can be read into anything until a proper update comes forth but who knows, it may not even happen this year until one of the drivers destroys their car.. which could be a god send actually.
Maybe both guys show collide safety and damage their cars enough that both get a new updated spec car earlier then planned.
