Mo couldn’t beat anyone and turned into a world beater.
Hassan has quality, but couldn’t beat the top guns or get gold. Now she is a world beater and breaking records
Donovan was quality but now he is destroying all comers and breaking AR.
Same thing with Centro, but he was smart enough to get out of dodge as well as MO.
Hassan and Yomif are highly trained by Salazar with everything they do, as well as Murphy, Rupp, and Hasay.
Nike running is really tainted, and throw Coleman and Gatlin in there as well.
I will not look at Hassan the same way or Yomif. Hassan couldn’t beat Obiri on her own natural ability.
