Methinks that you're talking through your ??? For example, Bottas would have been the 2019 world champ if Hamilton was not driving in a good car, or if he had been injured for a number of races...
nah dude. Bottas had no chance in 2019. and if LH was injured and missed say the last 5 races, Bottas would have found a way to skrew it up and Max would have ended up being the champion. or even LeClerc.
here is a nice graph to show what I mean
to better understand what I mean is replace LH/Alonso/Vettel/Kimi in 2012 with the driver you are considering is a possible champion. that pressure. that close a battle where its more than just the car or the driver, its what the Driver does under pressure. you can even do the same for 2018/2021 season to see what happens under the insane pressure. a true champion keeps their head level and makes no mistakes when there is a lot at stake.
where was bottas in 2021? not close enough.
where was Danny Ric in 2018? in a renault so not fighting at the sharp end.
there is sometimes more shown about the ability of a driver from how they handle pressure than we see when there is nothing at stake.
when Bottas was fighting for his seat for the 2022 season and his only way to keep his seat was to ensure LH became champion he folded under pressure now we have GR there.
when there was fighting for a tight championship in 2012 how did Alonso, Vettel, LH, Shumi and Rossberg handle it? they all gave more than 100% every race and created the greatest season in F1 history.
I said it before and I will say it again. 3 Drivers have the stones to fight and have shown it.
8 more have the potential based on F2 and the fight we have seen in them when the cars are not there.
the other 9 we have seen do not have what it takes to pull it off.
if there is some freaky development innovation that happend over the winter and by some miracle the Hass was a second clear of all the other cars at every track then sure Kmag/Hulk could become a champ, but the chances of that happening are as likely as the chances of me getting pregnant. in a competative season with multiple cars that are all fighting for the poles and wins every week there will be a clear seperation between those who can and those who cant. and until we get that repeat of the 2012 season we wont know.
