these "GSP and Frankie did this to BJ, so Khabib wins" arguments make no sense.
not only is Khabib's stand up nowhere near as good as GSP's or Frankie's, Khabib doesn't set up his takedowns with his striking even half as well as them.
i believe GSP has a better shot into his takedowns while Khabib is more tenacious and will continue to chain takedowns together until he gets his opponent down and Frankie is really right in the middle of them as far as takedowns, in my opinion.
to get BJ down you'll need a good stand up game and you'll need to be able to blend your stand up with your takedowns, you'll need to time a quick and explosive shot to catch BJ off guard when he thinks you're trying to strike him to be able to get him down, i don't think Khabib has the ability to do that.
BJ beats the shit out of Khabib and makes him look foolish.
