Does this mean Cole Hocker can threaten the world record?

Yes

Jakob essentially rabbited the race for Cole perfectly. Cole was hindered by Jakob when he wanted to start his kick, however.

I think he has something faster in him but not sub 3:26. I would love to be proven wrong though.

Cole Hocker today: 3:27.65, final 400m: 53.35ish, final 300m: 39.65ish

Hicham El Guerrouj in 1998: 3:26.00, final 400m: 53.27, final 300m: 39.66

That is gonna be a tall order

Sub-3:26 is a lot. It was his 3rd race in 5 days, and he did have a few inefficient points. The last 300 which included getting his stride blocked (cost him .2-.3) was overly fast at 39.6 to be maximal. His first 400 was inefficient at 14.5/14/13.5/13.6. From 400-1200 was pretty much perfect. I think he could trim it to 3:26.9 with the benefit of more rest and even pacing. That being said, from when Cole has time-trialed in the past he often would finish overly hard to be optimal (e.g. American indoor mile record attempts). So his best bet is being in a race with the other big 3 and duking it out.

I mean, he had a rabbit for 1420m. Doesn’t get much better than that.

How can it possibly be more rabbited than this?

Hell to the mf no
