Somewhat of a hot take...
If Lando pitted 1 lap after the first drivers stopped for inters, that would be massive for championship. Why? Because knowing Merc this season, they are not really mistake free tactics wise. If Lando pits there, Hamilton would most likely stay out and try to win the race (he said it on the radio at that point that slicks are fine). In that case... Lando wins the race easily, while Max finishes 2nd. Hamilton finishes 5th after the "Valtteri it's James".
