Thats fine if thats your opinion, but its certainly the minority opinion. Most people credit one of the guys that fought in a good hw division as the goat. Arlovski was definitely in his prime when they fought. Sylvia is arguable. Those were the only notable ufc guys at that time that Fedor hadn't fought. Cain and JDS hadn't emerged as the top guys until after Fedor was done.
For me personally, a title like goat takes more than beating Francis and going 2-1 with DC. Stipe has done little of note beyond that, unless you're really impressed by beating guys well past their prime.
