No he did not duck Big George. Tyson may have respected Foreman, as he was a histroian and love for the fighters, he would not duck him.

Tyson was after Holyfield and wanted the title back. Holyfield were using Foreman and got a title shot out of it. If Big George had wanted to fight Tyson he could easily have done it.

Tyson fought a far more dangerous fighter in Razor.

As for Lewis, I think tyson was in jail when Lewis, Bowe and Holyfield had their meetings. When Tyson did get the title he ducked Lewis.
