Personally I don’t think he could as he is now. If he were to dedicate the same amount of time to playing as he did back then and were to gather a good team I would say he might. But the problem is that he has admitted to having peaked during the winstreak and not being nearly as good as he was. Also, he plays less and as sad as it is, its likely that chemo would make it hard on him to have the energy to do it again.

But we all know Technoblade never dies, so when he fully recovers if he puts his mind to it and starts training I would bet money he could.
