The biggest question mark for the rematch is DC's ability to hand fight. DC can't win the striking game at distance, he's not long enough. He won't be able to take Jon down. His strategy, once again, will be to drive him against the cage with an underhook and beat him with the other hand. In the last fight, Jon countered this by reaching through the whizzer hand (his over hook), reaching across DC's body and grabbing DC's free hand. At that point, he was able to control both hands with his whizzer hand and strike with his knees and free hand to the open side. DC has to have a strategy to counter that, but I'm sure Greg Jackson has a list of counters to the potential counters DC may have. But that's where the fight will be won. I personally think the best bet will be DC +5.5. I think he will win a few rounds and it'll be closer.
