JDS will do this, JDS will do that, blahh blahh blahh arggghh
I think this is a very close fight.
Keys to Victory:-
JDS:-
Finding correct range to box,
avoid getting backed up against the cage(because then Overeem can pack some serious power behind his strikes and make the night really short for Cigano),
after the first round Overeem is very much likely to get slow which can add to JDS's good conditioning.
Overeem:-
Do not get into a fist fight(regardless of the K1 background, Overeem is still a kickboxer trying to out-box the most successful BOXER in UFC is not worth taking the risk, esp when tool in his arsenal is more to than just boxing),
improved gas tank is a must because he needs to do a lot of moving and throw a lot of kicks and knees to the body.
