Better chance at upset: Randy or Shields??
I go back and forth on this one: I think both have a chance at pulling off the upset. Randy took the fight with Machida, so obviously he sees something in Machida's game that he thinks he can possibly exploit for a win.
GSP is fighting a slightly bigger guy in Shields who hasn't lost in 7 years.
Who's got the better chance and why?
How would Randy beat Machida?
How would Shields beat GSP??
