His chain wrestling is perfect for MMA, no doubt. But the worry for Khabib would be firstly, GSP has much better stand up than him, he has amazing takedown defence but the biggest factor is he has worldclass takdowns for MMA himself and he's very good at controlling from the top. If GSP wants to double leg, i'd bet money on him getting it and having seen him roll with Danaher you can see he is really, really good. Personally, i think it's a really bad match up for Khabib. The fight i'd really like to see is Khabib vs Covington, i think that would do great numbers and i think he could take Colby down.
