Yes he definitely did and it looked like he lost steam for a few strides. I think he’s in WR shape right now
He is not as technically proficient a hurdler as Sydney. If he were, he could probably break the record. He's the fastest of the three over the flat 400
Can't compare women hurlders to mens. Vastly different due to the height differences. To say he's not as proficient as not true. Girls just walk over the hurdles.
