I see it this way: so far this year, he has had 2 wins, 5 podiums, 2 pole positions, 2 fastest laps, and a 1st and 2nd in sprint races.
With the exception of Monaco, he has finished in the top 6.
Sure, he's no Max Verstappen, and the team knows that, but he is putting his Red Bull towards the top pretty consistently. He gets screwed sometimes in qualifying, but he makes it up and scores good points for the team.
He's second in the driver's championship pretty handily as well.
Maybe I'm missing some context, so I'd like to know what the rest of you think about it.
The car is a rocketship... Yes he does recover decently enough in the race but he has missed Q3 in the last 5? Qualifyings. This is simply unacceptable given how dominant that car is. Maybe he is in a slump, that's fine but if this continues he needs to go.
