Of course GSP would want this fight...he made his name beating 170lbers who fought just like khabib. Putting top position grapplers either on their back or forcing them to stand is how GSP made his name coming up
hieron, Karo, trigg, sherk, hughes, kos, fitch, shields...that's how he made his name coming up. beating top position grapplers.
As good as khabib is, he's a 155 top position grappler.
