Brock Lesnar
Brock Lesnar, labeled by WWE as "the Next Big Thing," officially became the "big thing" at the 2002 Summerslam by defeating the Rock to become the youngest WWE Champion ever. With that said, the future looks incredibly bright for young Lesnar.
Brock has many factors going for him that ensure that he will remain a WWE top dog in 2007. First of all, he has the big man/powerhouse look that Vince McMahon loves. McMahon has, in the past, shown that he will push big men over and over again and give them many chances (just look at the Big Show). Lesnar fits that bill and even if he hits a hurdle in the future, odds are that WWE will continue to take chances on him. Lesnar also has a great look and a solid athletic background. He is a former NCAA amateur champion and that knowledge and experience will help him.
While Brock has yet to do anything memorable on the mic, he still has plenty of time to develop a solid promo style. He also has the benefit of having Paul Heyman as his mouthpiece until he is better able to speak for himself.
Due to his image, WWE has not really let Lesnar go crazy in the ring, and isolated him to a more lethargic style. However, Lesnar has shown in the past that he can work good matches for a big man, including the ability to hit an impressive top rope moonsault.
WWE has plenty of faith in “the Next Big Thing” and that, coupled with the many talents Lesnar already possess, pretty much makes Brock a lock to keep his spot as a major WWE star for the next five years.
