The letter why wrote:
It's not the athlete in particular, it's the fact that he's someone I've never heard of from Turkey.
From above comments, it seems like he's a young rising talent, so it's probably my fault that I haven't heard of him. Fair enough.
But Turkey has sent enough dirty athletes to championships for that to be a red flag on its own. For now I guess he deserves the benefit of the doubt.
He was a world youth champs silver medalist in 2007. European Junior champion in 2009.
He raced for Azerbaijan then. His dad/coach passed away. He moved to Turkey. People know about him.
