You never know. Ultimately the Merc was able to run longer and kinder on its tyres, and Hamilton may have been able to pull up to Raikkonen even without the assistance if Bottas for a few laps.
It looked to me that the Ferrari was superb on traction out of the slow corners but perhaps in the end that was their weakness as the cost of that grip was higher tyre wear and ultimately longevity.
In terms of points that Hamilton should have expected to be taking away from there, that race was an 20 point swing - I thought he’d be leaving Monza with a 10 point gap having finished second to Vettel, instead he’s got a 30 point gap. If my maths isn’t too wrong, that’s 5 second places and 2 wins would win Hamilton the championship, and that would have to be a reasonable bet even despite the current speed of the Ferrari in Vettel’s hands.
