His argument is that Rupp was tested "50 times last year".
He also says - "Ben Johnson was a doper, but clean runners today are running way faster than Ben Johnson did in 1988."
Um, which runners are clean breaking 9.8 these days? Gatlin? Bolt? Gay? Blake? This surprised me more than his comments about Rupp.
All of this coming from Bill Simmons' podcast with Gladwell, interesting listen -

Overall he paints a pretty rosy picture of the state of doping in T&F compared to what most LRCs would say.
