Lewis was clever, he would understand what he needs to do against Norton and put it on him early, he would understand that he doesn’t need to be cautious against Norton
The criteria to look for imo is more stationary passive punchers. Aggressive come forward punchers are a terrible mix for him and bonus points if they are even half decent at cutting off the ring and like to hammer away when they get their man on the ropes. Weaver is a good stylistic mention as he could almost go to sleep in there at times. Going one step further perhaps he'd go OK against guys with big power in only one hand. Maybe he'd fair better finessing his way out of trouble and getting into less in the first place. Guys like Shavers and Foreman came at him enormously hard from both sides. Maybe he'd go OK against a Coetzee. Personally i don't like his chances against Shavers at any point. Cooney maybe as he really was shot by then and was even put into trouble by Cooney's quite ordinary right hand if memory serves.
