The matchup we've all been waiting for is next Thursday in Lausanne with the US's two 20 year old sprint stars Michael Norman and Noah Lyles squaring off at 200m.
Lyles at first glance would be everyone's favorite as he's run 19.69 this year (and 19.83) while Norman has only clocked 19.84.
But Norman's run today was into a headwind (.6) while Lyle's best was with a 2.0 headwind. According to Jonas Mureika's wind calculator, Norman's run today in Paris is superior (worth 19.78 with no wind while Lyles run is worth 19.83 with no wind).
So who you got? Who will win and who are you rooting for?
