Overeem is the bookies favorite, but he has no ground game. It might only take one takedown to decide this, and Lesnar's takedowns and ground and pound are more effective than Werdum's. Ultimately, Lesnar will probably do whats good for the franchise, meaning he'll throw the fight and let the Reem face Velasquez/Dos Santos then come back for the Mir rematch.
I train with weights in the gym where overeem trains and being Dutch and mma fan I followed his career a bit and I can only say that he is an absolute monster. He just kills sparring partners which rotate all the time while he remains standing in the cage/ring.
1) No one should make random comments like many mainstream trolls and be taken seriously before you see
www.thereem.com documentary only then do you understand the transformation in the fighter from overeem 1.0 Light heavywight to Ubereem 2.0 who is HW champion in K1, Strikeforce and Dream, and see the difference in fights from the 2006 and before vs 2008 and beyond
2) Overeems ground game is sick! He is originally a grappler before coming into mma, he only never needs it so it doesnt show in fights since his preference is standing up and finishing with KOs. His ground game and TDD is top.
In the gym he taps all bjj black he brings in, even ADC world champion Einemo confirmed his in several interviews. Since Werdums game is ground only Reem nutralised this by TDD and cage control while landing some shots.
3) Brock has to get huge respect for the fights he been through in life on both personal and mma level. Nothing but respect for the guy who still is relatively inexperienced in mma but gets thrown to all former champions. Of course anyday brock hits someones chin, no matter who they will go down but to be honest I think this ight is very, very bad for Brock. Overeem TDD is solid, if anyone can take him down its Brock but then when they are down Reem is very good at blocking submissions, doing submissions himself and getting up. Of course he gets cardio issues like anybody else stopping TDs the whole match like werdums, but Brock isnt gonna throw 100 TD attempts without gassing himself.
As soon as the bet comes on bwin I put the house on Reem since I expect him to have favourable odds to to brocks popularity.
My expectation is a really fast win for the Reem by hard KO in the first round by either punch combo standing or knee/guillotine while Brock shoots for the TD.
The fight most interesting to me would be reem vs cain, since I dont consider JDS standup game a threat for the K1 WGP champ. Cains allroundness and cardio are a threat for all HWs
