Remind us again why Steve Magness is famous? Being a great coach? An excellent Journalist perhaps? No, he came to people's attention because of the accusations he made against Salazar and Rupp.
So why are you surprised he's accusing/insinuating that Ayana is doping?
It's what Magness is know for. It's what he does best.
That's not true. He was famous for his coaching and his website/book before. At least that's where I know him from.
