Sounds like Fedotov and KK were on the same CSKA team at the same time when Fedotov bought his military ID from some high ranking Russian military officer. He has since been arrested for selling the ID’s to many high profile Russian athletes. So it would not be surprising that KK at the very least was approached with the idea to buy one himself.
If any of this is true it could be a way for Russia to hold sway over their elite athletes. You either stay in your home country serve your military obligation and use your talent here or you will be charged with purchasing a fraudulent document to avoid the military.
It’s been reported Putin is in poor health and mentally unstable. It’s just a crapshoot right now over there. I would think someone would have been able to contact KK by now.
