they all dope. there's nothing interesting about it.
You’re mistaken. Take it from someone who would know. Outside of the former Soviet states and some developing nations, most athletes in this sport do it the right way. Those that push the regs or outright violate them are likely to be found out eventually, as Blessing was.
Unless you consider the US a "developing nation," you couldn't be more wrong.

No Michael Ohioze? He ran over the weekend so isn't injured. Seems odd do go from someone who ran 400m relay at the Tokyo Olympics to not even making the squad this time round. At 29, he's hardly over the hill.
