No one so far has been able to walk through JBJ's strikes, I don't see Sonnen being any different. JBJ is great at controlling distance, Rua - Page - Evans fights show that. I agree with the other poster in that this will be like his fight with Rua even though Rua and Sonnen are completely different fighters with different styles. Sonnen is going to be left crumbling on the floor.
