Lets be honest here, Leclerc still makes quite a few mistakes. Vettel has no excuses being a 4x wdc and all, but if Vettel where to leave and Leclerc being the automatic #1 driver, these mistakes need to be minimized. Ricciardo is a driver more than up to the task to win in the Ferrari and he makes minimal mistakes, + his overtaking skill is awesome. Ferrari with a car that's really top running (I do not mean dominant, but at least capable of competing for the win/front row each race), Ricciardo is a fantastic bet. IMO the only driver in the field today to drive the car to where it doesn't belong is Max.
