I don't think you can compare anyone to GSP heh, just saying I think he'd put up a formidable challenge to anyone he faces, including GSP
. Alves is also only 24 and his loss to Fitch came when he was 22 so he's got a lot of room to grow. He now also has a couple of pretty good notches on his belt: Karo and Hughes, both of whom he handled with relative ease.
