Mike Tyson in his prime would have destroyed Louis.. Louis was hittable ,and Tyson could crack that whip at 216 lbs, Tyson would have been bigger and stronger, and faster. Mike was one of the most devastating fighters in the history of boxing. Mike's prime was very short. 2 maybe 3 years, but you can't help but respect that speed , power, balance and leverage with which Tyson throw his punches. ! Mike had instincts and reflexes like a cat.. With Cuz and company Mike was a finally tuned machine, its only after he lost his mentor Cuz ( the source of his discipline ) that Mike started his downward spiral ... remember that even a Ferrari without proper maintenance goes to shit fairly quick !
