First and third exchange weren't particularly good, but the second one was really unprofessional looking. It feels weird watching such a bad race by such fast runners and being completely unsurprised by the result too. Feels like it's time to re-think a whole lot of stuff about the way they deal with relays at major world competitions. Between the terrible recent results and the depth of US sprinting, feels like the amount of options that would lead to simply "better" are pretty numerous.
