i think kevin lee, which is a much lesser of a wrestler showed us what control and cardio can do to tony
If you post a gif of you growing wings from your back and flying, I will believe you. No editting, raw footage.
Otherwise, that's not a lesson, its a delusion.
Anyway, sure he could lose the fights, that's possible. But we have no reason to believe it will be from lack of cardio as he has never in a single fight shown that weakness. On the contrary his work-rate has been off the charts. This fight will be skill based, I don't believe we will see either man get tired.
