Word is his cornerman wiped some on him, but it is also stated that the commission officials were on it when it happened and had it wiped off right then and there. Any residual vaseline left over wouldn't have had any effect on the fight at all, try it, a towel would wipe off 99% of anything on the skin.
I am sure BJ was in good shape, but when your getting dominated in every aspect it has to get to hurt your cardio no matter how good it is. When a 180lbs (fight weight) guy is on top of you, squeezing you, punching/elbowing you and you can do anything but take it your gonna get gassed from trying to defend and stay conscious. As for his trash talk, hey if its what he has to do before a fight who am I to say its wrong, but it is nice to see him get his due beats in retort.
Thiago Alves is probably the biggest Welterweight out there, if GSP walks around at 185-190lbs between fights, Alves has to be over 190, maybe 200 as he is one thick boy. I am with GSP (Canuck eh) but Alves has some real power, it will be a better test than BJ could have been, should be a very good fight.
