UFC rules vs pride rules

Yet pride existed for 10 years with people  roided to the gills ( I loved pride but some people where on the juice same as the ufc at the time ) . No one died . Like quadros said when wanderlei Silva fought hiromitsu kanehaea landing a soccer kick is not as easy as people think.

How many people where kod by a soccer kick? Not very many as I recall .

Less than a handful that made a priority to use it in all aspects in the game. Shogun wand we're that heavily used it.

Many moves are banned in UFC due to some reasons. They both have almost the same rule line. You can easily see through the table of content that Soccer rules (penalty kick) are also banned.
