So many questions will be answered. I firmly believe these are the two top heavyweights in the UFC so this fight is very intriguing.
I think Cain has more weapons, but I do believe JDS has the edge in power and if the fight stays standing will have an edge there, though it's a slim one. Cain's standup looks excellent thus far.
Cain will need his wrestling to win the fight, imo. I hope we see some jiu-jitsu from JDS.
