"world best" in the subject line is correct. Pity that former Olympians Ato and Sanya on NBCSN do not know that there is no official WR for the 300m.
Todd Harris is an idiot, said that Berry set a WR, but there are no indoor WRs in the throws except for the SP. Berry set a world best. Still impressive, sure.
Todd Harris also is complicit in the age-old TV formula of only showing one competitor, and not even bothering to tell the viewer who the other competitors are. Before you know it, sometimes even at the start of the very short clip about a vertical jump event, he tells you who has already won. Nice work, NBC, taking whatever drama there was in the event and destroying it. But it has always been that way (except for Dwight to some degree) and it will always be that way.
