I agree with them and also think guys like Tyson, Foreman and Liston deserve mention for the subtle art of intimidation. Liston was great at it and Foreman patterned himself off of Liston.

And for a guy like Tyson to dress in all black, come to the ring with just a cut towel over his head, his looks, ect had people intimidated almost as much as his power. When you have a great champ like Michael Spinks talking about how he fears for his health and safety going into a fight with you, you know you got into his head and he's beat already.
