Barstool Sports' Robbie Fox, host of "My Mom's Basement," joins Jim in-studio today to preview UFC 243. They're joined by a sleepy(?) Matt Serra, who Skypes in from Australia to make some predictions and lend insight about Al Iaquinta's training camp, ahead of his co-main event fight against Dan Hooker Saturday.  Then, Chris Weidman joins the show ahead of his Light Heavyweight debut against Dominick Reyes in Boston Oct. 18. Why does Weidman feel so confident about taking on an undefeated fighter at a new weight class? How's his health? Having already started a beef with Jon Jones, is there anything imminent? What's next for his fledgling acting career? Finally, another fighter/actor, Michelle Waterson, checks in ahead of her headline fight in Tampa Oct. 12 against Joanna Jedrzejczyk. Was she as surprised by Zhang Weili's TKO of Jessica Andrade as the rest of us were? What is her plan moving forward in the Strawweight division? Why should she be considered a title contender?
