You know, Arreola faired better than most of Vitali's past opponents, but man, the ref was not helping at all. He'd break them up instantly, but never gave any warnings for clinching.
Not saying that he was responsible for Arreola's loss, but Nipple's only chance in that fight was to get inside and do damage that way.
I'd like to see Wlad vs Vitali, and they've sounded more open to it then before, but at the end of the day, they are brothers, so probably not.
That would be a huge fight though.
