Evidently, BJ and Lyoto fought at WW (170lbs). Lyoto is a big guy, I think he's 6ft1in. He looks like 205 is a normal weight for him. I can't imagine him only weighing 170lbs. That's insane! Even at 170, Lyoto is too big of a guy for BJ to consider fighting. And, there's no way BJ could fight guys in 185 or 205. That's an unrealistic amount of weight for him to put on his 5ft9in frame. He doesn't even look cut at 170lbs. I think 155 is ideal for him, and he needs to leave the WW devision alone. GSP is a huge WW. His mere size, strength, and atheletisisim would pose a big problem for BJ. BJ would have to rely on skill alone to compete with guys in the WW, and though that can be enough at times, it will enevitably fail for him. Please, bring this up in your conversation!!!!!
