Let's break the fight down... Some strengths that they both possess is their grappling. Khabib's not going to ragdoll the bigger GSP. And GSP might not be able to outgrapple Khabib. It takes a better wrestler to take the guy down, it takes a way better wrestler to keep them down. And neither of them are way better at grappling. However GSP has the way better striking. I know this because GSP outstruck the (striker) champion (at 30+ pounds heavier) at the time to become the two division GOAT. Khabib doesn't possess that power to put GSP away.. and that's what it would take to beat GSP... If the grappling cancels out, GSP fans are stoked. In terms of what's better for the sport, we should all be rooting for GSP, 'cause this would be history in the making!
