The problem with modern sports is it isn't about having the best drivers or the best engineers yourself, it's about making sure your competition doesn't have the best. LH going to Ferrari wasn't about having LH drive the car to a championship level, it was destabilising Mercedes and team dominance. Red Bull is shattered because so many teams have picked at the carcass and McLaren were conveniently in the best place to benefit from the fall of Red Bull. If McLaren were not in front and Max was winning, he wouldn't be insulting the car and he'd be saying it's a dream to drive because it's winning.
Toto says he won't drop either driver, but just like Ferrari if you have the opportunity to deliver a fatal blow to one of your main competitors, you're going to take it unless you were already in a dominant position. It wouldn't surprise me if McLaren were sniffing even though they have two capable drivers under contract.
RB havent produced a good car, as of yet this year.
If Max was driving a McLaren, he would be winning every race so far.
