I don't know about this one. If Jack can get to Norton early and land consistenyly he stands a good chance of stopping him....but of course the key word is if..On the other hand if Ken can get his jab working and make good use of his size advantage I could see him boxing his way to a decision...again the key word is if. What bothers me is Norton's difficulty with big punchers who can back him up. If nothing else Dempsey can punch and has a pair of fast hands as well. I'll say Dempsey by early stoppage, somewhere between rounds 3 and 5. If not then Norton by decision.
