In what could be a classic wrestler versus wrestler match-up, what could be the deciding factor towards victory?
To find out, MMAInsider spoke to fellow UFC Hall of Famer Ken Shamrock to see who he feels will come out on top and why.
"I've got Randy," said Shamrock. "The main reason why is that Randy is very dedicated to his training.
"He's always in good shape, he's tough and he doesn't mind the hardness of Mark Coleman."
While Shamrock wasted little time in choosing Couture, he feels that Coleman is far from overmatched in some areas.
"Mark's probably stronger than him," stated Shamrock. "Randy's strong, don't get me wrong – but I think unless (Coleman has) lost that, he is a very strong individual and I think he would have the strength (advantage) on Randy."
Strength aside, Shamrock pointed out what could very well be Coleman's Achilles' heel and ultimately cost him the fight.
"I don't believe (Coleman) will be able to get out of the first round because Randy pushes the fight too much," said Shamrock. "I just don't believe that Mark is going to have the cardio to go with (Randy) out of the first round."
