I'll exclude Tsunoda because it's his first non-rookie season and new car regs. Stroll and Latifi have never beaten their respective team mates over the course of a full season, except Stroll against Sirotkin in 2018 (wow /s).
Now that I think about it, I bet Latifi is gone after this season. Williams said they no longer need to rely on pay driver money and the did sign F2's Logan Sargent to the Williams Academy. Realistically, they need to have two solid drivers to drag that shitbox around like Russell has the past 3 years.... or build a better car.
I really, really like Mick, but the sad truth is, he's not his father and won't probably have the career path his father did either.
