Mike Tyson used to say a calm fighter is a focused fighter. He encouraged a calm demeanour as did Cus.
I remember when a video game company wanted him to getall pumped up so it would look better for the video game, he refused Fedor doesnt do emotion
He knows he's a great fighter, has plenty of confidence going his way...He could smile, and wave at his opponent, and most would be scared. It's not about his look, but what he's accomplished, and what he knows he can do. His look does make it all the better though, and I enjoy it.
To me, he looks a little shy. I believe he is a focused, no nonsense, well conditioned fighter that believes in his abilities. I also think he shows signs of being a bit bashful. Fedor sometimes has a worried look to his eyes, but it seems to be toward his audience and surroundings.
