The comparison of BJJ and Sambo per se was more than stupid and I wonder why Kabeb would ever say something like that!? Like, its not even comparing apples and oranges, its even way worse and every casual, or Shermano, comparing those two would be totally torn in pieces if he would try to find a comparison.
One is a pure grappling based sport with no punches and kicks while the other one could be seen as a not that far away version of amateur MMA with Punches, Kicks and submission. I struggle to find an equally stupid comparison to show how stupid it was, not even "if Boxing was easy it would be called Kickboxing" can be used as example because they at least have in common that they are both pure stand up disciplines.
