Here's my take:
I think it should be Drago and Morris - I'll take Morris by a nose (a rather prominent Maltese nose). As a group, snooker players are just one notch above quilters in the fighting department.
Ralf against anyone - sorry, he was born to think, run racks, and maybe even run marathons, but he's defintely too civilized to be a fighter. My goodness, please do not put Ralf in the ring.
Darryl Peach - he can be a formidable man armed with a pacifier. Watch out for the head butt. Would hold his hands really high and circle them around like the old time boxers.
Rodney Morris - Hawaiians hate fighting. Too much work.
Corey Deuel - Corey is far too cool to fight and his backers will hire a lawyer to deliver the old one-two to anybody who cares to try him.
Shane - he would knock out a European with one really huge haymaker, thank them for giving him the opportunity, render CPR on them, and dust them off afterward.
Earl - Earl is the master of the "false charge". He knows just how far he can go at any given moment. It's all show - one pop in the nose and I think he would find the nearest exit in his green jogging suit.
Archer - I believe he would stand there and fight to the finish, ignore whatever pain his opponent inflicted, bleed buckets and just and jab them to death until they give up. Johhny has guts. He could be vulnerable when he bends over to pick the lint.
Feijin - Since Niels looks a lot like Dolph Lundgren,

He would probably do pretty well in the ring - the most formidable European for sure. Might fail the steroid testing.
The Russian - never underestimate a Russian's propensity for 3 things, fighting, drinking, and standing in line for luxury items. Pound for pound he would be a good fighter, but at 110 pounds he would have to match up against the wives for a fair fight.
The U.S. takes it easily in the ring.
