He WASN'T a good boxer... He was WIDE OPEN for left hooks...
He was a sitting duck for Mike Tyson... That's the 8th time he got dropped with left hooks... Williams ran into hooks left and right.. He ducked into them, got clipped leaning back from them, or just had his right hand down when they were coming... He never closed the hole... It was like Wladimir Klitschko before he got with Steward - straight lefts from a tall southpaw like Sanders ripped him out.. It's a very unusual angle and he couldn't pick them up.. Or Michael Moorer with straight shots down the middle, you couldn't miss him with his wide guard.. You can't have any holes or somebody is going to find them.. There's a 100 guys who can throw great left hooks and Tyson was one.
Williams looked great against Larry Holmes because Holmes didn't have a quick, powerful left hook... Holmes was old, soft, and slow... He was ready to be taken and had no strength and no gas - or he would have put Williams away in the 9th.
Williams was tall for his day... He had a fast jab and good feet... It takes more than 1, 2, or 3 skills to make a boxer.
