Who would take this respective match-up? Both fighters in their prime, it would be a tough call in my own opinion.
Ken Shamrock was in his prime about 12 years ago in 1994 with huge wins over Maurice Smith, Bas Rutten, Masakatsu Funaki, Manabu Yamada and others.
Mark Coleman started out his career with huge wins over Gary Goodridge, Dan Severn, and Don Frye. He lost three fights in a row to be removed from the UFC but came back with fighting in Pride in great condition with a 6 win streak.
Both fight close to each other's respective walking weight. Who would take it in your own opinion?
