Overeem's only weakness on the feet is that his hands are not the most technical. However he does have the flexability of using his kicks which is a weapon JDS rarely uses and hasn't encountered too often in his UFC career. At least at the level of Overeem. IN K-1 Overeem will get outpointed on a regular basis, only to KO his opponent with his friggin insane power.
JDS has never (to my knowledge) fought an opponent with the power (and technique to back it up) of Overeem. But in every case hwere its been said "he's never faced a guy like -insert adjective-" he's won so... I would never count him out in any situation.
I see Overeem throwing tons of kicks, and looking for the KO bomb. But I see JDS countering off that kick attempt and landing jabs in the early goings and in the latter goings, power punches behind it.
I think Overeem's chin is solid and it would take a serious flurry after a flush power punch to finish him. I can see JDS taking this one by UD. But if this one is finished, I'd say Overeem takes it by probability.
