If Brock takes Overeem down, it's all over

Agreed.

Brock lacks the experience. If Brock had the luxury to keep the fight in his domain (wrestling) then he is dominant. When he loses that luxury via punches or submission grappling then he lacks the experience.

Brock was preparing for JDS and now Overeem so it would be shocking if he hasn't been working hardcore on his striking for a good year. I think he knows he is weak there and thats why he brought in PAt Barry. Can't remember the rumours though - they didn't allow punching to the face or you got thrown out if you got too rough. The footage I've seen doesn't suggest this is the case.

 

Brock will never have great standup but if he can learn enough at least to make Reem worry about getting hit, like when he surprised Herring with that right hand, he also dropped mir and couture with punches so at least he can throw a punch with power. I don't think reem will let brock hit him like werdum was hitting him.
