6. Michael Johnson
Michael "Jack" (I'm not kidding or making that up) Johnson sustained Tyson's best ever finish. It's also the greatest punch Tyson ever landed guaranteed to crack up anyone you know that you show it to.
My honed journalistic instincts point to Johnson's ridiculously unfortunate hairdo deserving most of the credit for this. There's just something about the way his hair responds after Tyson delivers a sledge hammer-like right hand to Johnson's cheek that should come with a government warning you'll blow whatever you happen to be drinking out of your nose after viewing it.
This was Tyson at 19 shaping perhaps the greatest expectations ever placed on a heavyweight in the history of the sport. He was already a Sports Illustrated cover boy and was well on his way to the title, offering up warning to whoever stood in his path.
