Whilst I agree he doesnt deserve a rematch, neither did Cain, so on that basis JDS should be given the chance again.
How many people really saw the rematch going like that, not many, so to me a 3rd bout is a more interesting idea than the 2nd fight ever looked like it was going to be... until it actually happened.
Will Cain dominate JDS for another 5 rounds? Will JDS catch him and get an early KO? Who knows but I for one would love to see another fight.
But cain did have to beat bigfoot badly to get back to JDS so in turn it should be reem vs cain after he kills bigfoot, JDS vs Cormier/Barnett for a shot at champion or big nog/werdum winner
