Josh Kerr got interviewed by Citius Mag and had what seems to be a genuinely awful take, that Jakob gesturing to the crowd came from a place of insecurity. He believes Jakob did this either because he thought he was slipping from the center of attention, that he was running panicked, or that he wasn't comfortable in his running. He mentions himself doing it in the past, as well as Jakob doing it last year.
Frankly, this seems ridiculous. Maybe cockiness. Maybe. But insecurity? That makes no sense to me. He was the favorite and coming off a great season, so there's no way its because he "wasn't getting attention," a downright weird thing to posit. I think most were in agreement that he pretty easily went by everyone in the last 250 and looked good doing so, no signs of panic at all. So the only possible way he's right is if it is because Jakob felt bad and surprised himself with what he could do. This is possible as Jakob himself said he wasn't 100%, but it still makes no sense for Kerr to come to this conclusion based on last year where Jakob did it in the 5000 semis and then won pretty easily, clearly at 100%. Maybe that year he did it to regain some momentum after losing, but this year he had been undefeated and had just closed in a 52.6. Even if he was sick, I don't see how hyping up the crowd is going to make him feel any better about himself. It just doesn't make much sense.
Was Luis Grijalva insecure last year when he did the exact same thing as Jakob? Was Nordas insecure this year when he pumped his fist at the line in both the heats and the semis? Was everyone who has ever slowed up, pointed, waved to the crowd, or done a personal celebration insecure? It happens all the time, but when Jakob does it, its insecurity, disrespect, or some other pejorative thing that really isn't attributed to others who do similar things.
I guess we could defer to the expert on insecurity himself, Josh Kerr, who has time and time again has come out of a race and rambled about how he's actually 2 or 3 seconds faster, a 3:27 guy, currently a club with just 6(?) members.
