Yeah, no doubt it would score some PPV buys but it would be a terrible fight. Royce can't strike and knows it, he'd be pulling guard and butt scooting and clinch stalling all over the place. Ken can't strike either but he thinks he can, and he's probably the harder puncher at the very least with somewhat better technical boxing, and he has good sub defense. Ken would refuse to go to the ground and any time Royce went to the ground Ken would wave him back up. But Ken's probably not good enough to resist Royce's clinches and secure a KO on the feet.
All in all it would be a complete snoozefest as the two's abilities and gameplans cancelled each other out.
Everybody good, plenty of slaves for my robot colony?
