Sainz's 1 year loan farce shows Renault's approach to F1. He is a good fit to their Toyota style formula: mediocre team - mediocre but marketing fit drivers, not achieving anything, shifting goalposts, maybe we should get better ones and change approach, oops too late. They get headlines which is what matters, racing - not so much. Same goes for Ocon, both headlines and mediocrity.
I noticed that last two races by Leclerc, Silverstone when one corner was too difficult of a task and Germany's mess basically didn't happen in Only Good News Marketing (TM)
media. I think it's a mistake to ignore them, he's making his media based case of replacing Raikkonen stronger that way.
As for Ferrari if F1 were a sport based on merit and driven by sporting achievements we would have had Grosjean - Bottas line up for the last 4 seasons, much more interesting F1 and every chance for them to win something.
