Literally if Africans just threw away all perceived knowledge of tactics, and just focused on HUGGING the inside rail at all times in every race, they'd do so much better. Both Cheruiyot and Cheptegei were in the same fitness as Jakob in their respective races, and both punted the finals by running most of the race in lane 2 with no drafting. It's not complicated. Rail > drafting >> positioning. Unless you're such a heavy favorite that you want to minimize the chance of being tripped at all times, please don't run the whole damn race in lane 2...
