Chuck Norris was actually legitimate and a BJJ black belt. Both he and Bruce would get obliterated by any competent MMA guy today. If they trained for it than who knows but Bruce Lee was a philosopher/actor.
I will not agree that in prime shape Norris version might be easily get obliterated by anyone trained in MMA.
He had good shape and was able to met military tests norms.
He then had good gas tank and actually always had told how important is physical shape and S/C ...not only some secret death technique.
Yeah, then was easier to earn more money by showing some kicks and as actor....
However he was not weak dreamer.
Kicks alone, more looks that he had drilled enough long time just some kicks...still they were really well drilled power kicks....
With punches approx the same.
Yeah, I even do not know was he BJJ belt or no.
However reality is that he might had gave big problems for some local pros in both KB and pro boxing. Really very big problems.
If you have someone capable to do for example 30 full push ups and immediately after this 30 full pull ups....
Guy capable to climb up some 20 meters on rope with 100 lbs payload on lad and quickly.
Yeah, then semi contact stuff in western world was joke level and if you want to get money you compete under such rules.
Or might just to show some kicks and get money.
Or as an actor even more money.
