Overeem has a glass heart when things aren't going his way and suspect cardio, the worst things for both those is an ape like Lesnar on top of you. If he does get him down and establishes a dominan position he's ****ed.
Two behemoths with no cardio. One has no chin, the other no takedown defense. This ought to be really interesting and short lived.
You were trying to be funny, but this is how the fight will go. Roids, muscles, and submitting low level grapplers =/= NCAA Champion wrestling abitlity.
It really depends on the fighter. Getting up from the bottom, when you are truly on the bottom is about moving those hips. It astounds me how many fighters freeze. Partly because they don't have the stamina and partly because they don't have the confidence to defend the next move i.e. their back may be taken, they may give up side control etc Overeem has the length and strength to get off the bottom. IF he moves his hips enough and if he has the stamina is another thing. Brock isn't hardly a Gracie when it comes to sub threats and Reem knows his jits so he should actively be looking to get off the bottom.
Lesnar has no Chin and is scared to get punched in the face. He is not a fighter. Overeem by savage and embarrassing KO.
Lesnar's chin isn't that bad, he's not like Arlovski where he get's hit and is out cold. but he definatly doesn't like to get hit and will panic under in bad situation. And fighting Overeem is a guy who can put him in a bad situation, but it's about Lesnar being able to get him to the ground and control/keep him there. I don't think you can judge overeem by the werdum fight because that's not the reem that brock can expect to get his gameplan from.
