I haven't been impressed with his performances since Penn 2. I mean, the highlight packages they show speak for themselves. GSP's had how many exciting moments since then? A flash knockdown of Alves, a couple of submission attempts on Hardy, and what? Just lots of nullification of other fighters? Really getting tired of his style. You are right, he is looking more vulnerable than ever, and gets more tired. I think he might've peaked a few years ago. No doubt in my mind that he'd get demolished by Silva.
