Let's approach this logically. Let's assume we have this cycling who is going to become the GOAT but at this point in time, we don't know that yet. When does it become justifiable to start mentioning the cyling in the GOAT context? You are mentioning juniors - that is certainly not justifaiable. But surely you will agree it's not unjustifiable until the very moment his palmares actually exceed the previous GOAT's palmares?It isn't. Are we going to call junior cyclists the GOAT if they completely destroy the opposition?
So somewhere between his junior years and the moment a rider actually becomes the GOAT it becomes justifiable mentioning he might become the GOAT or come close to it. I think it's not an outrageous expectation for Pog and as a matter of fact - even the current GOAT appears to agree with that.
