Watch the posted vids of Tyson's style:
power and forward pressure
close range punches to head and body
close range combinations
Now look at Muay Thai:
powerful punches
knees to body both long and clinch
lo powerful hacking leg kicks
If Tyson was a kickboxer he would be a Thai boxer.
After applying Tyson's attack style in the boxing phase on pads and in sparring, apply his style to your Thai phase.
