We’ll also talk about how you get battle ready without sparring and the pros and cons of moving up in weight class. And we’re back with a new edition of Roundhouse, where Big Brown and KenFlo will have to Match nickname to fighter. And our Top 5 of the week is the Top 5 Finishers in the UFC, where Kenny and Brendan will also break down a fan’s list.
