The mightiest of mice made a mighty impact on Saturday in the octagon, and again today with The Sunday Junkie. The Sunday Junkie, MMAjunkie.com’s weekly reader-feedback feature, was dominated this week by submissions about Saturday’s UFC on FOX 8 card – in particular UFC flyweight champ “Mighty Mouse” Demetrious Johnson , who defended his title in dominant fashion against John Moraga , eventually forcing a fifth-round submission. But this week’s winner, Freddy Chavez, of Devonshire, England, wanted to talk about another big winner on Saturday’s card, Melvin Guillard . For his winning entry, Chavez wins a free one-year subscription to ” Fighters Only ” magazine, the world’s leading MMA and lifestyle magazine.
