I'm not a big follower of MMA, I just watch the big fights and I pick Overeem in this one.Lesnar is just brute strength, take down, ground n pound. Overeem has more to his game than Lesnar, so I pick Overeem but wouldn't be shocked if Lesnar wins. Lesnar needs to do some thing about his stand up, he can't just depend on his brute strength like he has so far.
