Cormier's resume is good. It's why I'm excited about his fight with Stipe. It's way bigger for me than GSP's fight with Bisping. Bisping was a very good win, being that it took place at 185 after a lay off. Bisping legitimately won his title, but he was far from being the best middleweight in the world. The entire top 10 would've been favored to defeat Bisping when he had the title. Stipe has defeated 4 or his top 5 contenders, and has established himself as the best heavyweight in the world. You can't come on here and say it's "comical how much GSPs resume is over rated" without explaining how it's overrated. Otherwise your opinion looks comical to any MMA fan. The UFC began ranking it's fighters in 2013, the year GSP retired. GSP defeated 5 of those fighters, including the top 3. I can't think of anyone relevant that would've been available to fight GSP, that he failed to face in his prime. He avenged the two losses of his career.
If stated such on several MMA forums and on here, whenever the GSP vs Silva debate comes up. I rate GSP and his resume, but some of his opponents get over rated vastly for the argument.
