Brock Lesnar is a bad dude.
He dominated college wrestling , exploded onto the WWE scene in 2002 and won the IWGP Heavyweight Championship in his first match in Japan. Lesnar almost made the Minnesota Vikings as a defensive tackle, and he was famous for his temper and bad attitude. This was all before he joined UFC and began his MMA career.
Lesnar became the UFC Heavyweight Champion in 2008 and was a fearsome force in that sport for three years.
Now, Brock is back in the WWE. He beat up HHH. He's pounded on John Cena and Shawn Michaels. He didn't get what he wanted, so he "quit." He's a bad man and a bad guy.
WWE is in desperate need of legitimate heels. With Lesnar, they have one waiting in the wings. How can Vince McMahon and company best utilize "The Beast?"
If I were making the decisions in Stamford, I'd capitalize on Lesnar's credibility as a legit tough guy. I'd book him into an MMA-style match or series of matches with one of the other bad asses on the roster. I might even consider having Lesnar issue an MMA challenge to the entire roster. Have him fight his way through a host of WWE contenders as a "warm-up" to what will eventually be his WrestleMania match.
Here are the 10 guys in WWE (or recently in WWE) that would be able to work convincing MMA-influenced matches with Lesnar.
