You had me until the last paragraph. When Samba was last healthy, he was consistently spanking Warholm every time they raced. He underperformed in Doha due to injury, but the idea that Warholm has been coming out on top every time against him is false. Benjamin also ran injured in Doha, but when he faced Warholm in Zurich last year it was a very close race.
Warholm is on fire and is easily #1 in the event right now, however the absence of Samba and Benjamin is causing people to get carried away. The race is not for silver. At their best, all 3 are gold medal threats capable of challenging the WR.
