Rewind: GSP Co-Author Justin Kingsley, Invicta's Shannon Knapp

A tumultuous week for UFC welterweight champion Georges St. Pierre is in the books, and the Sherdog Radio Network "Rewind" sought to bring a unique perspective to the conversation.

In a "Down to Business" edition of the program, host Jack Encarnacao welcomes Justin Kingsley, co-author of GSP's recently released book, "Way of the Fight." Kingsley speaks about St. Pierre's mental fortitude and the series of rumors floating around the champion, including commentary on Dana White's remarks after UFC 167.

Also on the show, Invicta FC President Shannon Knapp joins the show to discuss a seminal year for female MMA, including TUF 18, how Ronda Rousey and Miesha Tate have been portrayed, and what effect the addition of 115-pound women to the UFC will have on her organization. Knapp also discusses the landscape for a TV deal and the departure of her matchmaker.
