Omanyala has a challenger closer to home. Samuel Imeta(he is in the army) just clocked his first sub-10, and is 2 years younger than Omanyala. That means he is the youngest Kenyan to clock sub-10. Granted, it is all Omanyala's influence. People develop confidence about their ability when they see someone up close doing it.
The world's sprints is is jam-packed with crazy talent this year. With Fred Kerley, Noah Lyles, Trayvon Bromell, Christian Coleman, Omanyala, Oblique Seville - all capable of dipping under 9.8 - , the sprints have not looked this competitive in a long time.
