To date, there has never been a heel champion booked as dominantly as Brock Lesnar in WWE. After his initial losses to John Cena and Triple H, hes been on an incredible roll. He went through CM Punk, then accomplished the impossible when he ended The Undertakers legendary streak at WrestleMania. Almost as shocking was his match at SummerSlam where he beat John Cena like hed never been beaten before. That main event was no back-and-forth match, even-steven match, it was a massacre. With such a massive push behind Lesnar, whoever takes him down is going to benefit greatly, and potentially become a star. So which talent is most likely to do it? For starters, lets just hope that its not Cena. A win isnt going to make him any more popular. There wouldnt be much of a point in trading wins. Cena is already as big as hell ever be. Besides, the man is 37-years-old, and been on top for a decade. Its time for someone else to get their shot. And if it's not going to be an up-and-comer, there are a few other big name choices that could at least draw a big buyrate with a Lesnar showdown. From rookies to future main-eventers, to legends, here are the top eleven choices to defeat Brock Lesnar.
