Again I agree but disagree... Crocop is a presicion striker who is very fluid, most Heavies are not with the exception of Fedor... Look at Sylvia and Arlovski.. They are very Mediocre strikers at best and Mirko will be like a big fish in a small pond being in the UFC... I mean a kickboxer is no different than a regular Boxer.. if they are confident and pleased in there art why should they switch....

An effective ground game takes such a long time to master properly its a whole nother art in itself to master... Remy Bonjasky is my favorite Kickboxer he is definetly worldclass but he could do MMA and lose everytime I guess its a matter of personal choice for the athlete which art they want to master and stick with...

As far as Crocop he is definetly by far the 2nd best Heavy in the world to Fedor and then the rest of the field are pretty far behind
