Nope... the man had a plan come in at around 185 lbs, play it smart and out point him in enough rounds to score the upset but say F you to the belts.
GGG was 170 lbs and still tried his usual I will KO you in 6 or so rounds were he should have recognize the danger and play the points game better to win it more relaxed and not so close.
Either way he got the win even with his all in style and it was a good experience.
Oh and he was thinking the extra size is for an early all in strategy but it wasn't he came to box to a decision.. that's why GGG was a bit defensive in the first 2 rounds.
PS: Chocolito should have won that fight imo.
