This is a perfect storm, highly motivated athletes, four of them from 2 families, affluent community. These kids do a month long altitude camp, how many college teams do that?
Coach who is obsessive about his legacy and is training these kids at a high level, they travel to race all over the country. They do set up time trials, following BTC’s model, hopefully without the burritos.
and then you have “the shoes” which have helped everyone run faster. You can’t compare this era to any previous. Webb was better without a doubt, Ryun even better, South Eugene was better in my opinion. Times are almost irrelevant these days.
