He fills it with Vaseline to keep his hand moist for his wife, or, it's to cover up the mechanical right hand because he lost the real one in his duel with Darth Vader.
Im I the only one who thinks Johnson seems like a good character. He does seem like a funny guy. Staredowns mean nothing by the way. That crap is just for the cameras and to try and sell tickets to people who think that crap means something. Pacquiao can barely go through a staredown without breaking out into a smile. Doesnt seem to do him any harm. These guys are professional athletes. Astaring contest isnt going to make them fight any different! That being said,I still give Johnson little if any hope!
Don't underrate mental warfare. Some are immune, yes, but it works most of the time. Vitali is the master of intimidating, he's well known for delivering PAIN to opponents and always steps into his opponents personal zone, making physical contact, showing 'I'm already in your face buddy, and I'm going nowhere'. Johnson wore sunglasses all week as if he tried to avoid eye contact. Now the worst possible scenario happened the day before the fight: the guy you feared to have eye-contact with stepped into your face, removed your glasses from your face with his killer hands, and looked deep into your eyes with his stone cold killer look. And Johnson couldn't do **** about it. He was stunned. Nerves are a *****.
