Boxing: Is Shakur Stevenson the next big thing?; major upset in PBC (3/12)

Brian Campbell and Rafe Bartholomew get ready for featherweight titleholder Shakur Stevenson's first defense on Saturday against Miguel Marriaga and debate where the 22-year-old fits in as far as young fighters poised to take over the sport. The guys also react to Floyd Mayweather's claim that Terence Crawford is the pound-for-pound best fighter and review a wild weekend which saw unbeaten heavyweight Adam Kownacki suffer defeat and Scott Quigg announce his retirement following a TKO loss. ------------------------------------------ 'State of Combat' is available on Apple Podcasts, Spotify, Stitcher, Castbox, Bullhorn and wherever else you listen to podcasts.    Follow our hosts on Twitter: @BCampbellCBS, @Rafeboogs, @stateofcombat   For more boxing coverage from CBS Sports, visit https://www.cbssports.com/boxing/ To hear more from the CBS Sports Podcast Network, visit https://www.cbssports.com/podcasts/     To learn more about listener data and our privacy practices visit: https://www.audacyinc.com/privacy-policyLearn more about your ad choices.
