Canelo has weighed as much as 175 on fight night (unofficially) so, he'll be a lot bigger than Smith on fight night.... And I agree w/ the poster that said Smith will need a KO to win and keep his belt... I'm rooting for Smith to score the upset KTFO and for this PPV to tank..... There's no way this fight card should be a PPV, it's pretty lame top to bottom....
