"My division is pretty stack, I have a lot of challenges at 170, always"
is he talking about the UFC?
For 185, Marquardt, Cote, Loiseau, Kang, "and others" are his friends he won't fight. Yet Kang and Loiseau got dropped from the organization and the other two he named he really shouldn't have to worry about fighting.
Not hating, GSP is a tremendous athelete, ever since he focused more on wearing down his opponent and his ground game and less on standing and trading he's looked unstoppable, buuuuuuut he just seems to be fishing to avoid 185.
