How is it against good grapplers? Sure he tapped Tibau, but that is really it. If you want to use Tibau for a common denominator, same can be said about Johnson, and we all know how Ferguson beat him...... (sarcasm) I am not hating on Ferguson, but a lot of sherdog posters seem fixated that Ferguson can beat him from his back and even tap him too. But what grapplers has he beat? Sure, he can get to his feet, but even against Barboza, he tried a rolling heel hook (I think it was a heel hook, or kneebar), Barboza put all of his weight down and Ferguson was stuck there, he did strike Barboza from the position, but it seemed like he would have to change his position greatly to even have a chance of tapping him. I am not saying it is impossible that Ferguson taps him, but in reality; he has ridiculous submissions attempts from his back, however I don't think it will catch Khabib. If he tries these rolling attacks, he will just be stuck on bottom for a round as it wasn't all that long ago that Castillo held him down... Thoughts?
