I actually think they (UCI and WADA) should consider whom (which rider) it concerns. So if Rider A (here: Nairo) is positive, they should still count in what Nairo gave to global cycling in general, and cycling in Southern America, within the last ten years or so. Also Arkea and Samsic should be rewarded for pushing money into cycling, and not punished.
If Rider B (another rider, from another team) would be positive, they could still sanction him.
Punishing Nairo - IMHO - is not a correct decision, because he‘s a good guy from a good entourage.
