@The Seminole Hard Rock Live, Former two time HeavyWeight Champion of the world Shannon The Cannon Briggs takes on Vero Beach, FL native Michael Marrone. Marrone has a 60% KO rate and Briggs has some of the most first round knockouts in the world. I got Briggs by KTFO rd 1. He's in great shape and has some of the most hilarious YouTube videos ever. Thoughts on this bout anyone?
