Lesnar finished his amateur wrestling career as a two-time NJCAA All-American, two-time NCAA All-American, two-time Big Ten Champion, and the 2000 NCAA heavyweight champion with a record of 106-5 overall in four years of college.
This guy is clearly no joke.
But how serious are his mixed martial arts skills? In his first official MMA match, Brock defeated Min Soo Kim by submission (via strikes) in just more than one minute. Unfortunately, Min Soo Kim is not exactly top competition. Lesnar was dominant, but that was largely thanks to his wrestling technique. Many see Lesnar as the next UFC Heavyweight champ, but I plead you all to wait until he fights someone with ground skills before you give him the belt.
It will also be interesting to see how Lesnar deals with the UFC's illegal substance policy. In January 2001, Lesnar was arrested for receiving a large amount of steroids. The charges were later dropped when it was discovered that the illicit substance was, in fact, growth hormones.
Lesnar is a physical specimen with ridiculous wrestling skills. We have seen how effective fighters can be with a predominant wrestling background (Matt Hughes, Randy Couture) but it should be interesting to see how he can take a punch from a striker, which probably has not happened to him yet.
