DREAM wont bring in somebody they feel could beat Sakuraba. However, I wouldnt be at all shocked if Rubin somehow won this fight. Both are shot fighters though and I dont even remember the last time Rubin actually won a fight. Everytime he fights someone good, he loses, and loses badly.
This to me is still a interesting matchup. Likely what will happen is Sakuraba gets his trade mark single leg then Kimuras Williams but all fights start out on the feet as Tim Sylvia found out.
