Personally, I started having doubts about Barrera having a size advantage over Ward. Ward has always been a big SMW. It seems like Barrera is a small light heavy. Look at these pictures:

Barrera doesn't look much taller than Golovkin and doesn't have a big frame. I don't think that Barrera will be able to outpower Ward inside, so he just has a puncher's chance which is not high if Ward we know will show up.
