Let's see the facts. Ali, Holmes and Young had all kinds of troubles vs Norton, and all their 5 fights vs Kenny were very, very close. No one of these skilled boxers was even close to dominate Ken. For me, its quite obvious Ken's style is nightmare for every great HW in history who doesn't have great punching power. Anyway, how he'd do against other skilled HWs with average of little power?
I don't think so.. The three men you listed were probably the best heavyweight technicians of all time or at least ones with that combination of reasonable size and durability. I can't see Billy Conn, Gene Tunney, or Eddie Machen doing any better against Norton.
Evander had the power enough to stop him. Not with single shots but combinations. If he could move old foreman and did hurt tyson badly.i have few doubts about if he stops norton
