Yes they can.
Khabib doesn't have great shots. He shoots then comes into the clinch most of the time.
When he comes into the clinch he just does the same as Cain, DC, and Rockhold. Underhook one side and strike and pummel with the other. Do the same as Werdum did with Cain. Fight the free hand, control and smother it until he disengages or readjusts to take advantage of an oppertunity.
Werdum wasn't a great wrestler and did it to Cain almost flawlessly.
Branch was doing it to Rockhold great until he started striking with his free hand and stopped controlling Rockholds free hand, allowing Luke to pummel for the underhook which allowed him to get Branch down.
That is what it takes to shut down most of Khabibs game. You don't have to move backwards faster than he is moving forwards, you don't have to eliminate his forward pressure altogether, fighting the free hand in the clinch until you can circle out, and use feints to keep the pressure off and pick him off with counters.
I'm a huge Khabib fan but his opponents have bad gameplans against him most of the time.
